Right at the start of the pandemic, Dr. Anthony Fauci insisted that masks were unnecessary, which was in line with the preponderance of earlier evidence. Later, he sowed confusion — and distrust — by claiming he said that to discourage a run on masks, thus preserving supplies for the medical community. That mix-up put a stain on his credibility among those who were paying attention, and the reversal was simply bad policy given what is well established by the evidence on mask efficacy.

No Mas, No Mask!

Despite my own doubts about the efficacy of masks, I went along with masking for a while. It gave me a chuckle to see people wearing them outside, especially runners, or solo drivers. We knew by then that contracting Covid outside was highly unlikely. I was also amused by the idiotic protocols in place at many restaurants, where it was just fine to remove them once you walked a few feet to sit at your table, as if aerosols indoors were bound within narrow bands of altitude. Finally, I had reservations about the health consequences of frequent masking, which have certainly been borne out. Restricting air flow is generally not good for human health! Neither is trapping bits of sputum and hot, exhaled moisture rich in microbes right up against one’s muzzle. Still, I thought it polite to wear a mask in places of business, and I did so for a number of months.

In time it became apparent that the cloth and paper masks we were all wearing were a waste of effort. Covid is spread via fine aerosols and generally not droplets. That’s important because the masks in common use cannot block a sufficient level of Covid particles from escaping nor from penetrating through gaps and through the fiber itself. Neither can N95s if not fitted properly, as so many are not. And none of these masks can protect your eyeballs! When tens of thousands of tiny beads of aerosol are released with each cough or exhalation, a mask that stops 70% of them will not accomplish much.

The evidence began to accumulate that mask mandates were completely ineffective at “stopping the spread” of Covid. I then became an ardent anti-masker. I generally don’t wear them anywhere except medical buildings, and then only because I refuse to defer normal medical care, the consequences of which have been tragic during the pandemic. I have told clerks “I don’t need a mask”, which is true, and they have backed off. I have turned on my heal at stores that refuse to give on the issue, but like masks themselves, the signs on the doors are usually more for show than anything else. So I walk right past them.

Now, the Biden Administration has decided to provide to the public 400 million N95 masks — on the taxpayer! It’s a waste of time and money. But the timing is incredible, just as the Omicron wave crashes on it’s own. It will be one more worthless act of theatre. But don’t doubt for a moment that Joe Biden, when no one remembers the timing, will claim that this action helped defeat Omicron.

Mask Varieties

What is the real efficacy of masks in stopping the spread of Covid aerosol emissions? Cloth masks, including bandanas and scarves, are still the most popular masks. Based on casual observation, I suspect most of those masks aren’t washed as frequently as they should be. People hang them from their rear view mirrors for God knows how long. Beyond that, cloth masks tend to fit loosely and protect from aerosols about as well as the disposable medical or surgical masks that are now so common. Which is to say they don’t provide much protection at all.

But can that be? Don’t surgeons think they help? Well yes, because operating rooms can be very splattery places. Besides, it’s rude to sneeze into your patient’s chest cavity. Protection against fine aerosols? Not so much. “Oh, but should I double mask?”, you might ask? Gross! Just Shut*Up!

Face shields are “transparently” useless, offering no barrier against floating aerosols whatsoever except a fleeting moment’s protection against those blown directly into the wearer’s face. Then there are respirator masks: N95 and KN95, which are essentially the same thing. The difference is that KN95s must meet Chinese performance standards rather than U.S. standards. Both must filter and capture 95% of airborne particles as small as 0.3 microns. Covid particles are smaller than that, but the aerosol “beadlets” in which they are swathed may be larger, so the respirators would appear to be a big step up from cloth or surgical masks. R95 and P95 masks are made for protection against oil-based particles. They seem to be better overall due to thicker material and tighter fit with an overhead strap and extra padding.

Measuring Mask Efficacy

A thorough assessment of these mask types is documented in a 2021 paper published in The Physics of Fluids. Here are the baseline filtration efficiencies measured by the authors with an ideal mask fit relative to exhalation of 1 micron aerosols:

Cloth_______40%
Surgical____47%
KN95_______95%
R95_________96%

These are simply the filtration efficiencies of the respective barrier materials used in each type of mask, as measured by the researcher’s tests. Obviously, cloth and surgical masks don’t do too well. Unfortunately, even the N95 and KN95 masks never fit perfectly:

“It is important to note that, while masks … decrease the forward momentum of the respiratory jet, a significant fraction of aerosol escapes the masks, particularly at the bridge of the nose.”

Next, the authors assess the “apparent” filtration efficiencies of masks measured by relative aerosol concentrations in an enclosed space, measured two meters away from the source, after an extended period. This is a tough test for a mask, but it amounts to what people hope masks can accomplish: trapping aerosols containing bits of crap on material surrounding the nose and mouth, and for many hours. Here are the results:

Cloth___________9.8%
Surgical_______12.4%
KN95__________46.3%
R95____________60.2%
KN95-Gap______3.4%
KN95-Valve____20.3%

Cloth and surgical masks don’t do much to reduce the aerosol concentrations. Both the KN95 and R95 masks capture a meaningful share of the aerosols, but the R95 is a bit more effective. Remember, however, that the uncaptured share is a stand-in for the many thousands of virus particles that would remain suspended within the indoor space, so the filtration efficiency of the R95, while far superior to cloth or surgical masks, would do little to mitigate the spread of the virus. The KN95-Gap case is a test of a more “loosely fitted” mask with 3 mm gaps, which the authors say is realistic. Under those circumstances, the KN95 is about as good as nothing. Finally, the authors tested a well-fitted KN95 equipped with a one-way discharge valve. While its efficiency was better than cloth or surgical masks, it still performed poorly. The authors also found that various degrees of air filtration were far more effective in reducing aerosol concentrations than masks.

On the subject of mask fit, I quote Dr. Robert Lending, who has regularly chronicled pandemic developments for patients in his practice since the start of the pandemic:

“N95 type masks cannot be worn by men with beards. They must be so tightly fitted that they leave deep creases in your face. Prior to Covid-19, when hospital employees had to wear them for TB exposure prevention, they were told not to wear them for more than 3 hours at a time. They had to be fit-tested and gas leak-tested. … The N95 knockoffs such as the KN95s are not as good. N95 with valves do not protect others from you. There are now many counterfeit N95s for sale. … Obviously, N95s were never meant to be worn for 8-12 hours; and certainly not by youth and school children. If you are wearing an N95 and you can smell anything, such as aroma in a restaurant when you walk in, perfume, cologne, coffee, citrus, foul odors, etc.; then your fit is not correct and that N95 is worthless.”

Other Evidence

Another kind of evidence on mask efficacy is offered by randomized control trials (RCTs) in mitigating transmission of the influenza virus across a variety of settings, including hospital wards, schools, and neighborhoods of varying characteristics. A meta-analysis of 44 such RCTs published in the Cochran Library in late 2020 found that surgical masks make little or no difference to the spread of the virus. In a small set of RCTs from health care settings, the authors found that N95 and P95 masks perform about as well as surgical masks in limiting transmission.

An excellent review of research on mask efficacy appeared in City Journal last August. The author, Jeffrey H. Anderson, was fairly awestruck at the uniformity of RCT evidence that masks are ineffective. One well-publicized RCT purporting to show the opposite relied on effects that were negligible. Meanwhile, other research has shown that state-level mask mandates are ineffective at reducing the spread of the virus. Finally, here is a nice “cheat sheet” containing links to a number of mask studies.

Children

Children in many parts of the country are forced to wear masks at school. It’s well-established, however, despite wailing from teachers’ unions, that Covid poses extremely low risks to children. And there is no shortage of evidence that constant masking has extremely negative effects on children. The stupidity has reached grotesque proportions. Now, some school districts are proposing that children wear N95 masks! This is unnecessary and cruel, and it is ineffective precisely because children will be even less likely to use them properly than adults, who are generally not very good at it. From the last link:

“If N95s filter so well, why are respirators an ineffective intervention? Because masking is a behavioral intervention as much as a physical one. For respirators to work, they must be well fitting, must be tested by OSHA, and must be used for only short time windows as their effectiveness diminishes as they get wet from breathing.

“Fit requirements and comfort issues are untenable in children who have small faces and are required to wear masks for six or more hours each day. For these reasons, NIOSH specifically states that children should not use respirators, and there are no respirators that are approved for children. These views are shared by the California Department of public health. Concerns about impaired breathing and improper use outweigh potential benefits. There are no studies on the effectiveness of respirators on children because they are not approved for pediatric use.”

Rip It Off

At this point in the Omicron wave, which appears to have crested, we’re basically dealing with a virus that is less lethal than the flu and, for most people, comparable to the common cold. It’s a good time for the timid to shed their masks, which don’t help contain the spread of the virus to begin with. And masks do more harm than has generally been acknowledged, especially to children. So stop the bullshit. Take off your mask, and leave it off!

Censorship and Content Moderation in the Public Square

I’m probably as fed up with social media as anyone, given the major platforms’ penchant for censoring on the basis of politics, scientific debate, religion, and wokeism (or I should say a lack thereof). I quit Facebook back in January and haven’t regretted it. It’s frustratingly difficult to convince others to give it up, however, and I’ve tried. Ultimately, major user defections would provide the most effective means of restraining the company’s power.

Beyond my wild fantasies of a consumer revolt, I will confess to a visceral desire to see the dominant social media platforms emasculated: broken up, regulated, or even fined for proven complaints of censorial action. That feeling is reinforced by their anti-competitive behavior, which is difficult to curb.

Are There Better Ways?

While my gut says we need drastic action by government, my head tells me … not … so … fast! These are private companies, after all. I’m an adherent of free markets and private property, so I cannot abide government intrusions to force anyone to sponsor my speech using their private facilities. At the same time, however, our free speech rights must be protected in the “public square”, and the social media companies have long claimed that their platforms offer a modern form of the public square. If they can be taken at their word, should there be some remedy available to those denied a voice based upon their point-of-view by such a business? This seems especially pertinent when access to “public accommodations” is so critical to the meaning of non-discrimination under current law (not that I personally believe businesses should be forced to accommodate the specific demands of all comers).

In a lengthy and scholarly treatment of “Treating Social Media Platforms Like Common Carriers”, Eugene Volokh states the following about U.S. Supreme Court case law (pg. 41):

“Under PruneYard and Rumsfeld, private property owners who open up their property to the public (or to some segment of the public, such as military recruiters) may be required by state or federal law to share their real estate with other speakers.”

The Common Carrier Solution

Volokh’s article is very detailed and informative. I highly recommend it to anyone hoping to gain an understanding of the complex legal issues associated with the rights of big tech firms, their users, and other interested parties. His article highlights the long-standing legal principle that so-called “common carriers” in telecommunications cannot discriminate on the basis of speech.

Volokh believes it would be reasonable and constitutional to treat the big social media platforms as common carriers. Then, the platforms would be prohibited from discriminating based on viewpoint, though free to recommend material to their users. He also puts forward a solution that would essentially permit social media firms to continue to receive protection from liability for user posts like that granted under Section 230 of the Communications Decency Act:

“… I think Congress could categorically treat platforms as common carriers, at least as to their hosting function. But Congress could also constitutionally give platforms two options as to any of their functions: (1) Claim common carrier status, which will let them be like phone companies, immune from liability but also required to host all viewpoints, or (2) be distributors like bookstores, free to pick and choose what to host but subject to liability (at least on a notice-and- takedown basis).”

Economist Luigi Zingales emphasizes the formidable network externalities that give the incumbent platforms like Facebook a dominance that is almost unshakable. Zingales essentially agrees with Volokh, but he refers to common carrier status for what he calls the “sharing function” with Section 230-like protections, while the so-called “editing function” can and should be competitive. Zingales calls recommendations of material by a platform part of the editing function which should not be granted protection from liability. In that last sense, his emphasis differs somewhat from Volokh’s. However, both seem to think an change in the law is necessary to allow protections only where they serve the “public interest”, as opposed to protecting the private interests of the platforms.

The most destructive aspect of Section 230 immunity is the so-called “Good Samaritan” clause aimed at various kinds of offensive material (“… obscene, lewd, lascivious, filthy, excessively violent, harassing, or otherwise objectionable, whether or not such material is constitutionally protected.”), which the social media platforms have used as “a license to censor”, as Philip Hamburger puts it. Here, Eugene Volokh and others, including Supreme Court Justice Clarence Thomas, assert that this provision should not receive a broad interpretation in determining immunity for content moderation decisions. In other words, the phrase “otherwise objectionable” in the provision must be interpreted within the context of the statute, which, after all, has to do with communications decency! (Here again, I question whether the government can legitimately authorize censorship in any form.)

Arm of Government?

Viewpoint discrimination and censorship by the platforms is bad enough, but in addition, by all appearances, there is a danger of allowing companies like Facebook to become unofficial speech control ministries in the service of various governments around the world, including the U.S. Here is Vivek Ramaswamy’s astute take on the matter:

“… Facebook likely serves increasingly as the censorship arm of the US government, just as it does for other governments around the world.

In countries like India, Israel, Thailand, and Vietnam, Facebook frequently removes posts at the behest of the government to deter regulatory reprisal. Here at home, we know that Mark Zuckerberg and Sheryl Sandberg regularly correspond with US officials, ranging from e-mail exchanges with Dr. Anthony Fauci on COVID-19 policy to discussing “problematic posts” that “spread disinformation” with the White House.

If Zuckerberg and Sandberg are also directly making decisions about which posts to censor versus permit, that makes it much more likely that they are responsive to the threats and inducements from government officials.”

Even LinkedIn has censored journalists in China who have produced stories the government finds unflattering. Money comes first, I guess! I’m all for the profit motive, but it should never take precedence over fundamental human rights like free speech.

There is no question of a First Amendment violation if Facebook or any other platform is censoring users on behalf of the U.S. government, and Section 230 immunity would be null and void under those circumstances.

Elections … Their Way

On the other hand, we also know that platforms repeatedly censored distribution of the Trump Administration’s viewpoints; like them or not, we’re talking about officials of the executive branch of the U.S. government! This raises the possibility that Section 230 immunity was (or should have been) vitiated by attempts to silence the government. And of course, there is no question that the social media platforms sought to influence the 2020 election via curation of posts, but it is not clear whether that is currently within their rights under Section 230’s Good Samaritan clause. Some would note the danger to fair elections inherent in any platform’s willingness to appease authoritarian governments around the world, or their willingness and ability to influence U.S. elections.

Pledge of Facebook Allegiance

Some of our domestic social media companies have become supra-national entities without a shred of loyalty to the U.S. This article in The Atlantic, of all places, is entitled “The Largest Autocracy on Earth“, and it has a sub-heading that says it all:

“Facebook is acting like a hostile foreign power; it’s time we treated it that way.”

The article reports that Facebook’s Mark Zuckerberg has promoted the mantra “company over country”. That should disabuse you of any notion that he cares one whit about the ideals embodied in the U.S. Constitution. He is a child consumed with dominance, control, and profit for his enterprise, and he might be a megalomaniac to boot. If he wants to host social media relationships in this country, let’s make Facebook a common carrier hosting platform.

CDC Makes a Bum Lead Steer: Alternate Reality vs. The Herd

Jordan Schachtel enjoyed some schadenfreude last week when he tweeted:

“I am thoroughly enjoying the White House declaring COVID over and seeing the confused cultists having a nervous breakdown and demanding the continuation of COVID Mania.”

It’s quite an exaggeration to say the Biden Administration is “declaring COVID over”, however. They’re backpedaling, and while last week’s CDC announcement on masking is somewhat welcome, it reveals more idiotic thinking about almost everything COVID: the grotesquely excessive application of the precautionary principle (typical of the regulatory mindset) and the mentality of “zero COVID”. And just listen to Joe Biden’s tyrannical bluster following the CDC announcement:

“The rule is now simple: get vaccinated or wear a mask until you do.

The choice is yours.”

Is anyone really listening to this buffoon?Unfortunately, yes. But there’s no federal “rule”, unless your on federal property; it constitutes “guidance” everywhere else. I’m thankful our federalist system still receives a modicum of respect in the whole matter, and some states have chosen their own approaches (“Hooray for Florida”). Meanwhile, the state of the pandemic looks like this, courtesy of Andy Slavitt:

False Assertions

The CDC still operates under the misapprehension that kids need to wear masks, despite mountains of evidence showing children are at negligible risk and tend not to be spreaders. Here’s some evidence shared by Phil Kerpen on the risk to children:

The chart shows the fatality risk by age (deaths per 100,000), and then under the assumption of a 97% reduction in that risk due to vaccination, which is quite conservative. Given that kind of improvement, an unvaccinated 9 year-old child has about the same risk as a fully vaccinated 30 year-old!

The CDC still believes the unvaccinated must wear masks outdoors, but unless you’re packed in a tight crowd, catching the virus outdoors has about the same odds as a piano falling on your head. And the CDC insists that two shots of mRNA vaccine (Pfizer or Moderna) are necessary before going maskless, but only one shot of the Johnson and Johnson vaccine, even though J&J’s is less effective than a single mRNA jab!

Other details in the CDC announcement are worthy of ridicule, but for me the most aggravating are the agency’s implicit position that herd immunity can only be achieved through vaccination, and its “guidance” that the unvaccinated should be dealt with coercively, even if they have naturally-acquired immunity from an infection!

Tallying Immunity

Vaccination is only one of several routes to herd immunity, as I’ve noted in the past. For starters, consider that a significant share of the population has a degree of pre-existing immunity brought on by previous exposure to coronaviruses, including the common cold. That doesn’t mean they won’t catch the virus, but it does mean they’re unlikely to suffer severe symptoms or transmit a high viral load to anyone else. Others, while not strictly immune, are nevertheless unlikely to be sickened due to protections afforded by healthy vitamin D levels or because they are not obese. Children, of course, tend to be fairly impervious. Anyone who’s had a bout with the virus and survived is likely to have gained strong and long-lasting immunity, even if they were asymptomatic. And finally, there are those who’ve been vaccinated. All of these groups have little or no susceptibility to the virus for some time to come.

It’s not necessary to vaccinate everyone to achieve herd immunity, nor is it necessary to reach something like an 85% vax rate, as the fumbling Dr. Fauci has claimed. Today, almost 47% of the U.S. population has received at least one dose, or about 155 million adults. Here’s Kerpen’s vax update for May 14.

Another 33 million people have had positive diagnoses and survived, and estimates of seroprevalence would add perhaps another 30 million survivors. Some of those individuals have been vaccinated unnecessarily, however, and to avoid double counting, let’s say a total of 50 million people have survived the virus. Some 35 million children in the U.S. are under age 12. Therefore, even if we ignore pre-existing immunity, there are probably about 240 million effectively immune individuals without counting the remaining non-susceptibles. At the low end, based on a population of 330 million, U.S. immunity is now greater than 70%, and probably closer to 80%. That is more than sufficient for herd immunity, as traditionally understood.

The Herd Immunity Threshold

Here and in the following section I take a slightly deeper dive into herd immunity concepts.

Herd immunity was one of my favorite topics last year. I’m still drawn to it because it’s so misunderstood, even by public health officials with pretensions of expertise in the matter. My claim, about which I’m not alone, is that it’s unnecessary for a large majority of the population to be infected (or vaccinated) to limit the spread of a virus. That’s primarily because there is great variety in individuals’ degree of susceptibility, social connections, aerosol production, and viral load if exposed: call it heterogeneity or diversity if you like. Variation across individuals naturally limits a contagion relative to a homogeneous population.

Less than 1% of those who caught the virus died, while the others recovered and acquired immunity. The remaining subset of individuals most vulnerable to severe illness was thus reduced over time via acquired immunity or death. This is the natural dynamic that causes contagions to slow and ultimately peter out. In technical jargon, the virus reproduction rate “R” falls below a value of one. The point at which that happens is called the “herd immunity threshold” (HIT).

A population with lots of variation in susceptibility will have a lower HIT. Some have estimated a HIT in the U.S. as low as 15% -25%. Ultimately, total exposure will go much higher than the HIT, perhaps well more than doubling exposure, but the contagion recedes once the HIT is reached. So again, it’s unnecessary for anywhere near the full population to be immune to achieve herd immunity.

One wrinkle is that CIVID is now likely to have become endemic. Increased numbers of cases will re-emerge seasonally in still-susceptible individuals. That doesn’t contradict the discussion above regarding the HIT rate: subsequent waves will be quite mild by comparison with the past 14 months. But if the effectiveness of vaccines or acquired immunity wanes over time, or as healthy people age and become unhealthy, re-emergence becomes a greater risk.

Sub-Herd Immunity

A further qualification relates to so-called sub-herds. People are clustered by geographical, social, and cultural circles, so we should think of society not as a singular “herd”, but as a collection of sub-herds having limited cross-connectivity. The following charts are representations of different kinds of human networks, from Nathan D. Grawe’s review of “The Rules of Contagion, by Adam Kucharski:

Sub-herd members tend to have more degrees of separation from individuals in other sub-herds than within their own sub-herd. The most extreme example is the “broken network” (where contagions could not spread across sub-herds), but there are identifiable sub-herds in all of the examples shown above. Less average connectedness across sub-herds implies barriers to transmission and more isolated sub-herd contagions.

We’ve seen isolated spikes in cases in different geographies, and there have been spikes within geographies among sub-herds of individuals sharing commonalities such as race, religious affiliation, industry affiliation, school, or other cultural affiliation. Furthermore, transmission of COVID has been dominated by “super-spreader” events, which tend to occur within sub-herds. In fact, sub-herds are likely to be more homogeneous than the whole of society, and that means their HIT will be higher than we might naively calculate based on higher levels of aggregation.

We have seen local, state, or regional contagions peak and turn down when estimates of total incidence of infections reach the range of 15 – 25%. That appears to have been enough to reach the HIT in those geographically isolated cases. However, if those geographical contagions were also concentrated within social sub-herds, those sub-herds might have experienced much higher than 25% incidence by the time new infections peaked. Again, the HIT for sub-herds is likely to be greater than the aggregate population estimates implied, The upshot is that some sub-herds might have achieved herd immunity last year but others did not, which explains the spikes in new geographic areas and even the recurrence of spikes within geographic areas.

Conclusion

It’s unnecessary for 100% of the population to be vaccinated or to have pre-existing immunity. Likewise, herd immunity does not imply that no one catches the virus or that no one dies from the virus. There will be seasonal waves, though muted by the large immune share of the population. This is not something that government should try to stanch, as that would require the kind of coercion and scare tactics we’ve already seen overplayed during the pandemic. People face risks in almost everything they do, and they usually feel competent to evaluate those risks themselves. That is, until a large segment of the population allows themselves to be infantalized by public health authorities.

Give Back My Stolen Face

She looks good in a mask, and I grant you: masquerades often convey exciting undertones of sexual adventurism. But masquerades and masks should be novelties, not a constant way of life dictated by over-precautious public health authorities.

That brings me to the subject of an outdoor concert I’m attending with some friends on May 8th. It’s to be held at a grassy amphitheater along the Mississippi River in south St. Louis County. Unfortunately, the county health department imposes idiotic rules at this and other outdoor facilities. In the document at the link, it’s clear the rules were given some spin by the band who will perform that night, Jake’s Leg, a very good Grateful Dead cover band. And I get it: these guys just want to play music and perform for their fans, who will be happy to soak in the sounds, party, and dance the night away. Still, some of the rules are absurd and fly in the face of “the science”.

There is a certain libertarian streak among Grateful Deadheads, though in terms of realpolitik, probably the majority is of a more collectivist persuasion (not me). Some in the crowd will welcome the rules and might even go so far as to rat-out anyone whose behavior they find “unsafe”. Others will just go along with the rules as they interpret them. Some like me might push the envelope. But as the evening wears on… what a nice expression, … “as the evening wore on…”, it will be interesting to see whether forces tear loose from the prescriptive axis.

I’ve excerpted some of the rules below and added brief commentary. They appear in the order listed in the document, though it might seem a bit jumbled. I’m sorry to have left out most of the friendly color added by the band:

“Bring a cloth or paper face covering. You will not be allowed entry if you do not have one. Gaiters, bandanas and full-face shields are not acceptable as primary or only face covering. Face coverings must completely cover the nose and mouth. Children under 2 years old are not required to wear a face covering.”

The chances of contracting COVID outdoors are virtually nil, and don’t tell me we’re just learning these details … we’ve known that since almost the beginning of the pandemic. Second, in any case, cloth and paper masks are ineffective at stopping the aerosols responsible for most viral transmission. That’s been known for many years. Our public health experts are only now starting to admit these facts. Allowing toddlers to go maskless is the only concession, and it’s true that transmission by children is unlikely and COVID severity in children is very low. But that goes for older children as well, not just toddlers. Asymptomatic spread is similarly rare, so if you feel good enough to go (and they’ll check your temperature at the gate), you are unlikely to present a risk to anyone.

“Please bring small personal coolers only (no coolers w/ wheels) for your favorite beverages (cans and non- breakables please), along with snacks and food, chairs, blankets and personal use items for you and your small group.”

So, maybe not so bad… it’s about like the usual charade at restaurants: we must enter wearing masks, but then we can rip them off as soon as we find a spot to enjoy the music, our snacks, beverages and those all-important personal use items. Hmm, I guess the unsanitary passing of spleefs ist verboten. A hookah with several hoses could accommodate a small group, but that never goes over with an event staff! Edibles are fine!

“Have your ticket ready to be scanned … and always maintain at least 6 feet social distancing while you’re in line. Markers will be placed as a reminder for you.”

Even indoors, three feet of distancing has been acknowledged as adequate by the undeservedly celebrated Dr. Anthony Fauci.

“Please spread out and maintain at least six feet social distancing from other attendees outside of your small group. There is plenty of room to move and dance.”

More of the same hogwash. Note that the requirements offer no definition of “small group”. To appreciate the absurdity and unnecessary ass-covering inherent in all this, let me point out that my “small group” will consist of six or seven friends who haven’t met as a group in more than a year, We are almost sure to mix with other friends whom we’ll see at the show. So group members will migrate between groups, or small groups might merge into somewhat larger “small groups”. This will be happening all over, and it’s a pretty sure bet there will be lapses in mask compliance. If you happen to be spinning or dancing, the last thing you should do is wear a mask. You need oxygen, and you should avoid trapping hot breath and spittle right up against your face (see the latter part of this article).

“Once you’ve found a place to watch the show, please stay with your group at your area. If you must leave your space, you must wear a face covering at all times whenever you are not able to maintain at least 6 foot social distancing.”

Uh-huh… “Distancing” is not always clear-cut behavior. You pass people coming and going and dancing around. Are you “distancing” on average? Will you be ejected if you briefly come within a few feet of another concert-goer, sans mask? These are matters of uncertain degree, and it’s generally why police don’t enforce mask mandates in pedestrian areas, aside from a few draconian “mask traps” outside stores. Outdoors, it’s absurd.

“Please wash/sanitize your hands before and after using all restroom facilities. Always be kind, think of others and practice social distancing when waiting.”

Post-toilet hand washing is always a good practice, of course, but these guys are nuts! When I arrive at the restroom, I’m generally not worried about the remote chance that my hands will pass the virus to my genitals or vice-versa, and we know that the virus isn’t transmitted from surfaces. It’s also regrettable that masks and distancing will limit those sometimes entertaining conversations in bathroom lines.

“All attendees must adhere to these guidelines regardless of vaccination status.”

This also is sheer stupidity, and I’m complaining only because it reflects the “Zero COVID” mentality of the public health authorities holding us hostage. I guess I’d rather not bring my vaccination card along in any case, and at least they aren’t requiring “vaccine passports” for entry to the venue. But just in case I’m misunderstood, the chance that a fully vaccinated individual will catch or transmit the virus is very low and not even worthy of concern in any rational balancing of risk and benefit.

“Disclaimer: All venue initiatives to prevent the spread of COVID-19 are strictly followed and enforced. Those on premises are subject to compliance with all venue safety procedures and protocols. Non-compliance will result in refused entry or ejection from venue without refund. Upon purchasing tickets for the event, you acknowledge and agree to adhere to all venue policies.”

Again, as a practical matter, some of the rules listed above are virtually unenforceable, but we’ll see how the evening unfolds with a crowd of free-wheeling Deadheads. It could be all strangers stopping strangers, just to bump their elbows. Either way, if past is prelude, the amphitheater will be something of a heart-of-gold land.

Intelligent public policy is all too often undermined by policy makers incapable of properly assessing risks. The Biden Administration is setting new standards in this regard with its so-called “return to school” effort. It’s difficult to know how much of it is sheer stupidity and how much is pandering to teachers unions. Equal parts is probably a reasonable approximation.

The public teachers unions have consistently opposed reopening since remote learning began last spring, despite reams of data showing the safety of school environments. Even the CDC agrees! Oh, but wait: the CDC just issued new guidelines for reopening, which among other things require six feet of distancing rather than the three feet Director Rochelle Walensky claimed was adequate just a few months ago. Obviously, this reduces the number of students many existing school buildings can accommodate.

COVID transmission in schools is “extremely rare”. And in addition, remote education is sorely lacking in effectiveness. Teachers who truly care about educating their students should be giving the unions an earful. Not only has learning been compromised, but remote learning has increased the achievement gap between the best students and those in the lower part of the distribution.

Private schools have been open and as the map above shows, public schools in a number of states are largely open to in-person learning. Where that’s not the case, public school buildings are often still being used by children. They’re under the supervision of adults, but not teachers! As Matt Welch says:

“… many of the empty school buildings in largely closed districts are not in fact empty—they are filled with kids, being supervised by adults, just not adults who belong to teachers unions.”

Incidentally, many adults with children now at home, rather than in school, have been forced to leave the labor force, and many of them are women. As Michael Watson asks, why are advocates of working women so silent on this point? And this is to say nothing of the health care workers diverted, during a pandemic, from patient care by the need to manage children at home.

In December, Joe Biden promised to reopen “most” K – 12 schools within his first one-hundred days in office. Shortly after his inauguration, that promise became “most” K – 8 schools. As Welch notes, now the goal has been made a bit more precise, and it’s a complete sham: the Administration wants at least half of schools to be “open” for in-person learning at least one day a week! But we’re already well ahead of that! (And see here.)

On top of that, the federal government is playing the interloper here: reopening is not a federal decision. Ah, but Biden wants $130 billion in federal money earmarked to aid schools in their reopening efforts. Anthony Fauci has decided the stimulus is necessary for schools to reopen, his latest in a series of embarrassing policy flip-flops. The funds targeted at schools would be spent in a variety of ways, including PPE, COVID tests, new ventilation systems, and enhancement of remote learning to accommodate smaller (and distanced) in-person class sizes. Some of the funds are likely to make their way into teacher pay and to shore up pensions. One thing is certain: the unions want that money, and they will come back for more!

The unions also argue that teachers should be prioritized for vaccines, which would place them ahead of groups facing drastically higher risks. This is flat-out callous, insane, and evil. Again, the risk of COVID to teachers and children is low, while the elderly population faces staggeringly higher risks. Vaccinating teachers ahead of the elderly would cost many thousands of lives on balance.

This article from Education Next by Darrell Bradford describes the conditions for reopening demanded by teachers unions as the culmination of several years of activism. The unions contributed mightily to Joe Biden’s election campaign, of course. Their overwrought posture on teacher safety aside, the unions’ obstinance on the question of reopening is intended as leverage in the legislative push for Biden’s school aid package. Here’s Bradford:

“In other words, if you’ve wondered what a national teacher strike might look like and what might cause teachers across the country to arrest local economies and subject millions of students to instruction that may lock in deep learning losses, it’s just like this.”

The schools are safe, remote learning is substandard, and isolation is damaging to children’s’ emotional well being. Union demands for continuing limitations on in-person learning and requirements for reopening are not just unreasonable, but dastardly. That the Biden Administration is crafting its reopening policy and spending initiatives to appease the unions is motivated more by politics than the interests of children and their families. It’s time for parents and other true advocates to let their school administrators, elected representatives, and government officials know that the unions do not have their children’s interests at heart. And well-informed teachers should demand that their union representatives stop playing politics with the educational goals to which they’ve devoted their careers.

Revisiting Excess Mortality

All-Cause Mortality, Anthony Fauci, Ben Martin, Covid-19, Excess Deaths, Joe Biden, Lockdowns, Non-Pharmaceutical interventions, Pandemic

In early December I said that 2020 all-cause mortality in the U.S. would likely be comparable to figures from about 15 years ago. Now, Ben Martin confirms it with the chart below. Over time, declines in U.S. mortality have resulted from progress against disease and fewer violent deaths. COVID led to a jump in 2020, though some of last year’s deaths were attributable to policy responses, as opposed to COVID itself.

Here’s an even longer view of the trend from my post in December (for which 2020 is very incomplete):

As Martin notes sarcastically:

“Surprising, since the US is undergoing a ‘century pandemic‘ – In reality it is an event that’s unique in the last ‘15 years’”

The next chart shows 2020 mortality by month of year relative to the average of the past five years. Clearly, excess deaths have occurred compared to that baseline.

Using the range of deaths by month over the past 20 years (the blue-shaded band in the next chart), the 2020 figures don’t look quite as anomalous.

Finally, Martin shows total excess deaths in 2020 relative to several different baselines. The more recent (and shorter) the baseline time frame, the larger the excess deaths in 2020. Compared to the five-year average, 364,000 excess deaths occurred in 2020. Relative to the past 20 years, however, 150,000 excess deaths occurred last year. While those deaths are tragic, the pandemic looks more benign than when we confine our baseline to the immediate past.

Moreover, a large share of these excess deaths can be attributed to non-COVID causes of death that represent excesses relative to prior years, including drug overdoses, suicide, heart disease, dementia, and other causes. As many as 100,000 of these deaths are directly attributable lockdowns. That means true excess deaths caused by COVID infections were on the order of 50,000 relative to a 20-year baseline.

As infections subside from the fall wave, and as vaccinations continue to ramp up, some policy makers are awakening to the destructive impacts of non-pharmaceutical interventions (lockdown measures). The charts above show that this pandemic was never serious enough to justify those measures, and it’s not clear they can ever be justified in a free society. Yet some officials, including President Biden and Anthony Fauci, still labor under the misapprehension that masks mandates, stay-at-home orders, and restaurant closures can be effective or cost-efficient mitigation strategies.

Fauci Flubs Herd Immunity

Acquired Immunity, Anthony Fauci, Covid-19, Herd Immunity, Hererogeneity, HIT, Masks, Max Planck Institute, Measles, MMR Vaccine, R0, Reproduction Rate, T-Cells. Pre-Immunity, Tyler Cowen, Vaccinations. Fragile Immunity

Anthony Fauci has repeatedly increased his estimate of how much of the population must be vaccinated to achieve what he calls herd immunity, and he did it again in late December. This series of changes, and other mixed messages he’s delivered in the past, reveal Fauci to be a “public servant” who feels no obligation to level with the public. Instead, he crafts messages based on what he believes the public will accept, or on his sense of how the public must be manipulated. For example, by his own admission, his estimates of herd immunity have been sensitive to polling data! He reasoned that if more people reported a willingness to take a vaccine, he’d have flexibility to increase his “public” estimate of the percentage that must be vaccinated for herd immunity. Even worse, Fauci appears to lack a solid understanding of the very concept of herd immunity.

Manipulation

There is so much wrong with his reasoning on this point that it’s hard to know where to start. In the first place, why in the world would anyone think that if more people willingly vaccinate it would imply that even more must vaccinate? And if he felt that way all along it demonstrates an earlier willingness to be dishonest with the public. Of course, there was nothing scientific about it: the series of estimates was purely manipulative. It’s almost painful to consider the sort of public servant who’d engage in such mental machinations.

Immunity Is Multi-Faceted

Second, Fauci seemingly wants to convince us that herd immunity is solely dependent on vaccination. Far from it, and I’m sure he knows that, so perhaps this too was manipulative. Fauci intimates that COVID herd immunity must look something like herd immunity to the measles, which is laughable. Measles is a viral infection primarily in children, among whom there is little if any pre-immunity. The measles vaccine (MMR) is administered to young children along with occasional boosters for some individuals. Believe it or not, Fauci claims that he rationalized a requirement of 85% vaccination for COVID by discounting a 90% requirement for the measles! Really???

In fact, there is substantial acquired pre-immunity to COVID. A meaningful share of the population has long-memory, cross-reactive T-cells from earlier exposure to coronaviruses such as the common cold. Estimates range from 10% to as much as 50%. So if we stick with Fauci’s 85% herd immunity “guesstimate”, 25% pre-immunity implies that vaccinating only 60% of the population would get us to Fauci’s herd immunity goal. (Two qualifications: 1) the vaccines aren’t 100% effective, so it would take more than 60% vaccinated to offset the failure rate; 2) the pre-immune might not be identifiable at low cost, so there might be significant overlap between the pre-immune and those vaccinated.)

Conceptual Confusion

Vaccinations approaching 85% would be an extremely ambitious goal, especially if it is recommended annually or semi-annually. It would be virtually impossible without coercion. While more than 91% of children are vaccinated for measles in the U.S., it is not annual. Thus, measles does not offer an appropriate model for thinking about herd immunity to COVID. Less than half of adults get a flu shot each year, and somewhat more children.

Fauci’s reference to 85% – 90% total immunity is different from the concept of the herd immunity threshold (HIT) in standard epidemiological models. The HIT, often placed in the range of 60% – 70%, is the point at which new infections begin to decline. More infections occur above the HIT but at a diminishing rate. In the end, the total share of individuals who become immune due to exposure, pre-immunity or vaccination will be greater than the HIT. The point is, however, that reaching the HIT is a sufficient condition for cases to taper and an end to a contagion. If we use 65% as the HIT and pre-immunity of 25%, only 40% must be vaccinated to reach the HIT.

Heterogeneity

A recent innovation in epidemiological models is the recognition that there are tremendous differences between individuals in terms of transmissibility, pre-immunity, and other factors that influence the spread of a particular virus, including social and business arrangements. This kind of heterogeneity tends to reduce the effective HIT. We’ve already discussed the effect of pre-immunity. Suppose that certain individuals are much more likely to transmit the virus than others, like so-called super-spreaders. They spur the initial exponential growth of a contagion, but there are only so many of them. Once infected, no one else among the still-susceptible can spread the virus with the same force.

Researchers at the Max Planck Institute (and a number of others) have gauged the effect of introducing heterogeneity to standard epidemiological models. It is dramatic, as the following chart shows. The curves simulate a pandemic under different assumptions about the degree of heterogeneity. The peak of these curves correspond to the HIT under each assumption (R0 refers to the initial reproduction number from infected individuals to others).

Moderate heterogeneity implies a HIT of only 37%. Given pre-immunity of 25%, only an additional 12% of the population would have to be infected or vaccinated to prevent a contagion from gaining a foothold for the initial exponential stage of growth. Fauci’s herd immunity figure obviously fails to consider the effect of heterogeneity.

How Close To the HIT?

We’re not as far from HITs as Fauci might think, and a vaccination goal of 85% is absurd and unnecessary. The seasonal COVID waves we’ve experienced thus far have faded over a period of 10-12 weeks. Estimates of seroprevalence in many localities reached a range of 15% – 25% after those episodes, which probably includes some share of those with pre-immunity. To reach the likely range of a HIT, either some additional pre-immunity must have existed or the degree of heterogeneity must have been large in these populations.

But if that’s true, why did secondary waves occur in the fall? There are a few possibilities. Of course, some areas like the upper Midwest did not experience the springtime wave. But in areas that suffered a recurrance, perhaps the antibodies acquired from infections did not remain active for as long as six months. However, other immune cells have longer memories, and re-infections have been fairly rare. Another possibility is that those having some level of pre-immunity were still able to pass live virus along to new hosts. But this vector of transmission would probably have been quite limited. Pre-immunity almost surely varies from region to region, so some areas were not as firmly above their HITs as others. It’s also possible that infections from super-spreaders were concentrated within subsets of the population even within a given region, in certain neighborhoods or among some, but not all, social or business circles. Therefore, some subsets or “sub-herds” achieved a HIT in the first wave, but it was unnecessary for other groups. In other words, sub-herds spared in the first wave might have suffered a contagion in a subsequent wave. And again, reinfections seem to have been rare. Finally, there is the possibility of a reset in the HIT in the presence of a new, more transmissible variant of the virus, as has become prevalent in the UK, but that was not the case in the fall.

Fragility

Tyler Cowen has mentioned another possible explanation: so-called “fragile” herd immunity. The idea is that any particular HIT is dependent on the structure of social relations. When social distancing is widely practiced, for example, the HIT will be lower. But if, after a contagion recedes, social distancing is relaxed, it’s possible that the HIT will take a higher value at the onset of the next seasonal wave. Perhaps this played a role in the resurgence in infections in the fall, but the HIT can be reduced via voluntary distancing. Eventually, acquired immunity and vaccinations will achieve a HIT under which distancing should be unnecessary, and heterogeneity suggests that shouldn’t be far out of reach.

Conclusion

Anthony Fauci has too often changed his public pronouncements on critical issues related to management of the COVID pandemic. Last February he said cruises were fine for the healthy and that most people should live their lives normally. Oops! Then came his opinion on the limited effectiveness of masks, then a shift to their necessity. His first position on masks has been called a “noble lie” intended to preserve supplies for health care workers. However, Fauci was probably repeating the standing consensus at that point (and still the truth) that masks are of limited value in containing airborne pathogens.

This time, Fauci admitted to changing his estimate of “herd immunity” in response to public opinion, a pathetic approach to matters of public health. What he called herd immunity was really an opinion about adequate levels of vaccination. Furthermore, he neglected to consider other forms of immunity: pre-existing and already acquired. He did not distinguish between total immunity and the herd immunity threshold that should guide any discussion of pandemic management. He also neglected the significant advances in epidemiological modeling that recognize the reality of heterogeneity in reducing the herd immunity threshold. The upshot is that far fewer vaccinations are needed to contain future waves of the pandemic than Fauci suggests.

The Pernicious COVID PCR Test: Ditch It or Fix It

Minimally Infectious, Brown University, CDC, Coronavirus, Covid-19, Cycle Threshold, DNA, Elon Musk, Eurosurveillence, False Positives, Molecular Tests, New York Times, PCR Tests, Portugal, Replication Cycles, RNA, SARS-CoV-2

We have a false-positive problem and even the New York Times noticed! The number of active COVID cases has been vastly exaggerated and still is, but there is more than one fix.

COVID PCR tests, which are designed to detect coronavirus RNA from a nasal swab, have a “specificity” of about 97%, and perhaps much less in the field. That means at least 3% of tests on uninfected subjects are falsely positive. But the total number of false positive tests can be as large or larger than the total number of true positives identified. Let’s say 3% of the tested population is truly infected. Then out of every 100 individuals tested, three individuals are actively infected and 97 are not. Yet about 3 of those 97 will test positive anyway! So in this example, for every true infection identified, the test also falsely flags an uninfected individual. The number of active infections is exaggerated by 100%.

But again, it’s suspected to be much worse than that. The specificity of PCR tests depends on the number of DNA replications, or amplification cycles, to which a test sample is subjected. That process is illustrated through three cycles in the graphic above. It’s generally thought that 20 – 30 cycles is sufficient to pick-up DNA from a live virus infection. If a sample is subjected to more than 30 cycles, the likelihood that the test will detect insignificant dead fragments of the virus is increased. More than 35 cycles prompts real concern about the test’s reliability. But in the U.S., PCR tests are regularly subjected to upwards of 35 and even 40-plus cycles of amplification. This means the number of active cases is exaggerated, perhaps by several times. If you don’t believe me, just ask the great Dr. Anthony Fauci:

“It’s very frustrating for the patients as well as for the physicians … somebody comes in, and they repeat their PCR, and it’s like [a] 37 cycle threshold, but you almost never can culture virus from a 37 threshold cycle. So, I think if somebody does come in with 37, 38, even 36, you got to say, you know, it’s just dead nucleotides, period.“

Remember, the purpose of the test is to find active infections, but the window during which most COVID infections are active is fairly narrow, only for 10 – 15 days after the onset of symptoms, and often less; those individuals are infectious to others only up to about 10 days, and most tests lag behind the onset of symptoms. In fact, infected but asymptomatic individuals — a third or more of all those truly infected at any given time — are minimally infectious, if at all. So the window over which the test should be sensitive is fairly narrow, and many active infections are not infectious at all.

PCR tests are subject to a variety of other criticisms. Many of those are discussed in this external peer-review report on an early 2020 publication favorable to the tests. In addition to the many practical shortfalls of the test, the authors of the original paper are cited for conflicts of interest. And the original paper was accepted within 24 hours of submission to the journal Eurosurveillance (what a name!), which should raise eyebrows to anyone familiar with a typical journal review process.

The most obvious implication of all the false positives is that the COVID case numbers are exaggerated. The media and even public health officials have been very slow to catch onto this fact. As a result, their reaction has sown a panic among the public that active case numbers are spiraling out of control. In addition, false positives lead directly to mis-attribution of death: the CDC changed it’s guidelines in early April for attributing death to COVID (and only for COVID, not other causes of death). This, along with the vast increase in testing, means that false positives have led to an exaggeration of COVID as a cause of death. Even worse, false positives absorb scarce medical resources, as patients diagnosed with COVID require a high level of staffing and precaution, and the staff often requires isolation themselves.

Many have heard that Elon Musk tested positive twice in one day, and tested negative twice in the same day! The uncomfortable reality of a faulty test was recently recognized by an Appeals Court in Portugal, and we may see more litigation of this kind. The Court ruled in favor of four German tourists who were quarantined all summer after one of them tested positive. The Court said:

“In view of current scientific evidence, this test shows itself to be unable to determine beyond reasonable doubt that such positivity corresponds, in fact, to the infection of a person by the SARS-CoV-2 virus.”

I don’t believe testing is a bad thing. The existence of diagnostic tests cannot be a bad thing. In fact, I have advocated for fast, cheap tests, even at the sacrifice of accuracy, so that individuals can test themselves at home repeatedly, if necessary. And fast, cheap tests exist, if only they would be approved by the FDA. Positive tests should always be followed-up immediately by additional testing, whether those are additional PCR tests, other molecular tests, or antigen tests. And as Brown University epidemiologist Andrew Bostom says, you should always ask for the cycle threshold used when you receive a positive result on a PCR test. If it’s above 30 and you feel okay, the test is probably not meaningful.

PCR tests are not ideal because repeat testing is time consuming and expensive, but PCR tests could be much better if the number of replication cycles was reduced to somewhere between 20 and 30. Like most flu and SARS viruses, COVID-19 is very dangerous to the aged and sick, so our resources should be focused on their safety. However, exaggerated case counts are a cause of unnecessary hysteria and cost, especially for a virus that is rather benign to most people.

On COVID, NPIs, and “Human” Data Points

The other day a friend told me “your data points always seem to miss the people points.” He imagines a failure on my part to appreciate the human cost of the coronavirus. Evidently, he feels that I treat data on cases, hospitalizations, and deaths as mere accounting issues, all while emphasizing the negative aspects of government interventions.

This fellow reads my posts very selectively, hampered in part by his own mood affiliation. Indeed, he seems to lack an appreciation for the nuance and zeitgeist of my body of blogging on the topic… my oeuvre! This despite his past comments on the very things he claims I haven’t mentioned. His responses usually rely on anecdotes relayed to him by nurses or doctors he knows. Anecdotes can be important, of course. But I know nurses and doctors too, and they are not of the same mind as his nurses and doctors. Anecdotes! We’re talking about the determination of optimal policy here, and you know what Dr. Fauci says about relying on anecdotes!

Incremental Costs and Benefits

My friend must first understand that my views are based on an economic argument, one emphasizing the benefits and costs of particular actions, including human costs. COVID is dangerous, but primarily to the elderly, and no approach to managing the virus is free. Here are two rather disparate choices:

Mandated minimization of economic and social interactions throughout society over some time interval in the hope of reducing the spread of the virus;
Laissez faire for the general population while minimizing dangers to high-risk individuals, subject to free choice for mentally competent, high-risk individuals.

To be clear, #2 entails all voluntary actions taken by individuals to mitigate risks. Therefore, #1 implies a set of incremental binding restrictions on behavior beyond those voluntary actions. However, I also include in #1 the behavioral effects of scare mongering by public officials, who regularly issue pronouncements having no empirical basis.

The first option above entails so-called non-pharmaceutical interventions (NPIs) by government. These are the elements of so-called lockdowns, such as quarantines and other restrictions on mobility, business and consumer activity, social activities, health care activities, school closures, and mask mandates. NPIs carry costs that are increasing in the severity of constraints they impose on society.

And before I proceed, remember this: tallying all fatal COVID cases is really irrelevant to the policy exercise. Nothing we do, or could have done, would save all those lives. We should compare what lives can be saved from COVID via lockdowns, if any, with the cost of those lockdowns in terms of human life and human misery, including economic costs.

Economic Losses

NPIs involve a loss of economic output that can never be recovered… it is gone forever, and a loss is likely to continue for some time to come. That sounds so very anodyne, despite the tremendous magnitude of the loss involved. But let’s stay with it for just a second. The loss of U.S. output in 2020 due to COVID has been estimated at $2.5 trillion. As Don Boudreaux and Tyler Cowen have noted, what we normally spend on safety and precautionary measures (willingness-to-pay), together with the probabilities of losses, implies that we value our lives at less than $4 million on average. Let’s say the COVID death toll reaches 300,000 by year-end (that’s incremental in this case— but it might be a bit high). That equates to a total loss of $1.2 trillion in life-value if we ignore distinctions in life-years lost. Now ask this: if our $2.5 trillion output loss could have saved every one of those 300,000 lives, would it have been worth it? Not even close, and the truth is that the sacrifice will not have saved even a small fraction of those lives. I grant, however, that the economic losses are partly attributable to voluntary decisions, but goaded to a great extent by the alarmist commentary of public health officials.

The full depth of losses is far worse than the dollars and cents comparison above might sound. Output losses are always matched by (and, in value, are exactly the same as) income losses. That involves lost jobs, lost hours, failed businesses, and destroyed careers. Ah, now we’re getting a bit more “human”, aren’t we! It’s nothing short of callous to discount these costs. Unfortunately, the burden falls disproportionately on low-income workers. Our elites can mostly stay home and do their jobs remotely, and earn handsome incomes. The working poor spend their time in line at food banks.

Yes, government checks can help those with a loss of income compete with elites for the available supply of goods, but of course that doesn’t replace the lost supply of goods! Government aid of this kind is a palliative measure; it doesn’t offset the real losses during a suspension of economic activity.

Decimated Public Health

The strain of the losses has been massive in the U.S. and nearly everywhere in the world. People are struggling financially, making do with less on the table, depleting their savings, and seeking forbearance on debts. The emotional strains are no less real. Anxiety is rampant, drug overdoses have increased, calls to suicide hotlines have exploded, and the permanence of the economic losses may add to suicide rates for some time to come. Dr. Robert Redfield of the CDC says more teenagers will commit suicide this year than will die from COVID (also see here). There’s also been a terrifying escalation in domestic abuse during the pandemic, including domestic homicide. The despair caused by economic losses is all too real and should be viewed as a multiplier on the total cost of severe NPIs.

More on human costs: a health care disaster has befallen locked-down populations, including avoidance of care on account of panic fomented by so-called public health experts, the media, and government. Some of the consequences are listed here. But to name just a few, we have huge numbers of delayed cancer diagnoses, which sharply decrease survival time; mass avoidance of emergency room visits, including undiagnosed heart attacks and strokes; and unacceptable delays in cardiac treatments. Moreover, lockdowns worldwide have severely damaged efforts to deal with scourges like HIV, tuberculosis, and malaria.

The CDC reports that excess mortality among 25-44 year-olds this year was up more than 26%, and the vast bulk of these were non-COVID deaths. A Lancet study indicates that a measles outbreak is likely in 2021 due to skipped vaccinations caused by lockdowns. The WHO estimates that 130,000,000 people are starving worldwide due to lockdowns. That is roughly the population of the U.S. east coast. Again, the callousness with which people willfully ignore these repercussions is stunning, selfish and inhumane, or just stupid.

Excess Deaths

Can we quantify all this? Yes we can, as a matter of fact. I’ve offered estimates in the past, and I already mentioned that excess deaths, COVID and non-COVID, are reported on the CDC’s web site. The Ethical Skeptic (TES) does a good job of summarizing these statistics, though the last full set of estimates was from October 31. Here is the graphic from the TES Twitter feed:

Note particularly the huge number of excess deaths attributable to SAAAD (Suicide, Addiction Abandonment, Abuse and Despair): over 50,000! The estimate of life-years lost due to non-COVID excess deaths is almost double that of COVID deaths because of the difference in the age distributions of those deaths.

Here are a few supporting charts on selected categories of excess deaths, though they are a week behind the counts from above. The first is all non-COVID, natural-cause excess deaths (the vertical gap between the two lines), followed by excess deaths from Alzheimer’s and dementia, other respiratory diseases, and malignant neoplasms (cancer):

The clearest visual gap in these charts is the excess Alzheimer’s and dementia deaths. Note the increase corresponding to the start of the pandemic, when these patients were suddenly shut off from loved ones and the company of other patients. I also believe some of these deaths were (and are) due to overwhelmed staff at care homes struck by COVID, but even discounting this category of excess deaths leaves us with a huge number of non-COVD deaths that could have been avoided without lockdowns. This represents a human cost over and above those tied to the economic losses discussed earlier.

Degraded Education and Health

Lockdowns have also been destructive to the education of children. The United Nations has estimated that 24 million children may drop out of school permanently as a result of lockdowns and school closures. This a burden that falls disproportionately on impoverished children. This article in the Journal of the American Medical Association Network notes the destructive impact of primary school closures on educational attainment. Its conclusions should make advocates of school closures reconsider their position, but it won’t:

“… missed instruction during 2020 could be associated with an estimated 5.53 million years of life lost. This loss in life expectancy was likely to be greater than would have been observed if leaving primary schools open had led to an expansion of the first wave of the pandemic.“

Lockdown Inefficacy

Lockdowns just don’t work. There was never any scientific evidence that they did. For one thing, they are difficult to enforce and compliance is not a given. Of course, Sweden offers a prime example that draconian lockdowns are unnecessary, and deaths remain low there. This Lancet study, published in July, found no association between lockdowns and country mortality, though early border closures were associated with lower COVID caseloads. A French research paper concludes that public decisions had no impact on COVID mortality across 188 countries, U.S. states, and Chinese states. A paper by a group of Irish physicians and scientists stated the following:

“Lockdown has not previously been employed as a strategy in pandemic management, in fact it was ruled out in 2019 WHO and Irish pandemic guidelines, and as expected, it has proven a poor mitigator of morbidity and mortality.”

One of the chief arguments in favor of lockdowns is the fear that asymptomatic individuals circulating in the community (and there are many) would spread the virus. However, there is no evidence that they do. In part, that’s because the window during which an individual with the virus is infectious is narrow, but tests may detect tiny fragments of the virus over a much longer span of time. And there is even some evidence that lockdown measures may increase the spread of the virus!

Lockdown decisions are invariably arbitrary in their impact as well. The crackdown on gyms is one noteworthy example, but gyms are safe. Restaurants don’t turn up in many contact traces either, and yet restaurants have been repeatedly implicated as danger zones. And think of the many small retailers shut down by government, while giant competitors like Wal-Mart continue to operate with little restriction. This is manifest corporatism!

Then there is the matter of mask mandates. As readers of this blog know, I think masks probably help reduce transmission from droplets issued by a carrier, that is, at close range. However, this recent Danish study in the Annals of Internal Medicine found that cloth masks are ineffective in protecting the wearer. They do not stop aerosols, which seem to be the primary source of transmission. They might reduce viral loads, at least if worn properly and either cleaned often or replaced. Those are big “ifs”.

To the extent that masks offer any protection, I’m happy to wear them within indoor public accommodations, at least for the time being. To the extent that people are “scared”, I’m happy to observe the courtesy of wearing a mask, but not outside in uncrowded conditions. To the extent that masks are required under private “house rules”, of course I comply. Public mask mandates outside of government buildings are over the line, however. The evidence that those mandates work is too tenuous and our liberties are too precious too allow that kind of coercion. And private facilities should be subject to private rules only.

QED

So my poor friend is quite correct that COVID is especially deadly to certain cohorts and challenging for the health care community. But he must come to grips with a few realities:

The virus won’t be defeated with NPIs; they don’t work!
NPIs inflict massive harm to human well-being.
Lockdowns or NPIs are little or no gain, high-pain propositions.

The rejection of NPI’s, or lockdowns, is based on compelling “human” data points. As Don Boudreaux says:

“The lockdowns and other restrictions on economic and social activities are astronomically costly – in a direct economic sense, in an emotional and spiritual sense, and in a ‘what-the-hell-do-these-arbitrary-diktats-portend-for-our-freedom?’ sense.”

This doctor has a message for the those denizens of social media with an honest wish to dispense helpful public health advice:

“Americans have admitted that they will meet for Thanksgiving. Scolding and shaming them for wanting this is unlikely to slow the spread of SARS-CoV-2, though it may earn you likes and retweets. Starting with compassion, and thinking of ways they can meet, but as safely as possible, is the task of real public health. Now is the time to save public health from social media.”

Policymakers, public health experts, and the media responded to the coronavirus in ways that have often undermined public health and magnified the deadly consequences of the pandemic. Below I offer several examples of perverse politics and policy prescriptions, and a few really bad decisions by certain elected officials. Some of the collateral damage was intentional and motivated by an intent to inflict political damage on Donald Trump, and people of good faith should find that grotesque no matter their views on Trump’s presidency.

Politicized Treatment

The smug dismissal of hydroxychloraquine as Trumpian foolishness was a crime against humanity. We now know HCQ works as an early treatment and as a prophylactic against infection. It’s has been partly credited with stanching “hot spots” in India as well as contributing strongly to control of the contagion in Switzerland and in a number of other countries. According to epidemiologist Harvey Risch of the Yale School of Public Health, HCQ could save 75,000 to 100,000 lives if the drug is widely used. This is from Dr. Risch’s OpEd in Newsweek:

“On May 27, I published an article in the American Journal of Epidemiology (AJE) entitled, ‘Early Outpatient Treatment of Symptomatic, High-Risk COVID-19 Patients that Should be Ramped-Up Immediately as Key to the Pandemic Crisis.’ That article, published in the world’s leading epidemiology journal, analyzed five studies, demonstrating clear-cut and significant benefits to treated patients, plus other very large studies that showed the medication safety. …

Since [then], seven more studies have demonstrated similar benefit. In a lengthy follow-up letter, also published by AJE, I discuss these seven studies and renew my call for the immediate early use of hydroxychloroquine in high-risk patients.”

Risch is careful to couch his statements in forward-looking terms, but this also implies that tens of thousands of lives could have been saved, or patients might have recovered more readily and without lasting harm, had use of the drug not been restricted. The FDA revoked its Emergency Use Authorization for HCQ on June 15th, alleging that it is not safe and has little if any benefit. An important rationale cited in the FDA’s memo was an NIH study of late-stage C19 patients that found no benefit and potential risks to HCQ, but this is of questionable relevance because the benefit appears to be in early-stage treatment or prophylaxis. Poor research design also goes for this study and this study, while this study shared in some shortcomings (e.g., and no use of and/or controls for zinc) and a lack of statistical power. Left-wing outlets like Politico seemed almost gleeful, and blissfully ignorant, in calling those studies “nails in the coffin” for HCQ. Now, I ask: putting the outcomes of the research aside, was it really appropriate to root against a potential treatment for a serious disease, especially back in March and April when there were few treatment options, but even now?

Then we have the state governors who restricted the use of HCQ for treating C19, such as Gretchen Whitmer (MI) and Steve Sisolak (NV). Andrew Cuomo (NY) decided that HCQ could be dispensed only for hospital use, exactly the wrong approach for early stage treatment. And all of this resistance was a reaction to Donald Trump’s optimism about the promise of HCQ. Yes, there was alarm that lupus patients would be left without adequate supplies, but the medication is a very cheap, easy to produce drug, so that was never a real danger. Too much of the media and politicians have been complicit in denying a viable treatment to many thousands of C19 victims. If you were one of the snarky idiots putting it down on social media, you are either complicit or simply a poster child for banal evil.

Seeding the Nursing Homes

The governors of several states issued executive orders to force nursing homes to accept C19 patients, which was against CMS guidance issued in mid-March. The governors were Andrew Cuomo (NY), Gretchen Whitmer (MI), Gavin Newsom (CA), Tom Wolf (PA), and Phil Murphy (PA). This was a case of stupidity more than anything else. These institutions are home to the segment of the population most vulnerable to the virus, and they have accounted for about 40% of all C19 deaths. Nursing homes were ill-prepared to handle these patients, and the governors foolishly and callously ordered them to house patients who required a greater level of care and who represented an extreme hazard to other residents and staff.

Party & Protest On

Then of course we had the mayor of New York City, Bill De Blasio, who urged New Yorkers to get out on the town in early March. That was matched in its stupidity by the array of politicians and health experts who decided, having spent months proselytizing the need to “stay home”, that it was in their best interests to endorse participation in street protests that were often too crowded to maintain effective social distance. That’s not a condemnation of those who sought to protest peacefully against police brutality, but it was not a good or consistent recommendation in the domain of public health. Thankfully, the protests were outside!

Testing, Our Way Or the Highway

The FDA and CDC were guilty of regulatory overreach in preventing early testing for C19, and were responsible for many lives lost early in the pandemic. By the time the approved CDC tests revealed that the virus was ramping up drastically in March, the country was already behind in getting a handle on the spread of the virus, quarantining the infected, and tracing their contacts. There is no question that this cost lives.

Masks… Maybe, But Our Way Or the Highway

U.S. public health authorities were guilty of confused messaging on the efficacy of masks early in the pandemic. As Joel Zinberg notes in City Journal, Anthony Fauci admitted that his own minimization of the effectiveness of masks was motivated by a desire to prevent a shortage of PPE for health care workers:

“In discouraging mask use, Fauci—for decades, the nation’s foremost expert on viral infectious diseases—was not acting as a neutral interpreter of settled science but as a policymaker, concerned with maximizing the utility of the limited supply of a critical item. An economist could have told him that there was no need to misinform the public. Letting market mechanisms work and relaxing counterproductive regulations would ease shortages. Masks for health-care workers would be available if we were willing to pay higher prices; those higher prices, in turn, would elicit more mask production.”

Indeed, regulators made acquisition of adequate supplies of PPE more difficult than necessary via compliance requirements, “price gouging” rules, and import controls.

Bans on Elective Surgery

Another series of unnecessary deaths was caused by various bans on elective surgeries across the U.S. (also see here), and we’re now in danger of repeating that mistake. These bans were thought to be helpful in preserving hospital capacity, but hospitals were significantly underutilized for much of the pandemic. Add to that the fright inspired by official reaction to C19, which keeps emergency rooms empty, and you have a universe of diverse public health problems to grapple with. As I said on this blog a couple of months ago:

“… months of undiagnosed cardiac and stroke symptoms; no cancer screenings, putting patients months behind on the survival curve; deferred procedures of all kinds; run-of-the-mill infections gone untreated; palsy and other neurological symptoms anxiously discounted by victims at home; a hold on treatments for all sorts of other progressive diseases; and patients ordinarily requiring hospitalization sent home. And to start back up, new health problems must compete with all that deferred care. Do you dare tally the death and other worsened outcomes? Both are no doubt significant.”

Lockdowns

The lockdowns were unnecessary and ineffectual in their ability to control the spread of the virus. A study of 50 countries published by The Lancet last week found the following:

“Increasing COVID-19 caseloads were associated with countries with higher obesity … median population age … and longer time to border closures from the first reported case…. Increased mortality per million was significantly associated with higher obesity prevalence … and per capita gross domestic product (GDP) …. Reduced income dispersion reduced mortality … and the number of critical cases …. Rapid border closures, full lockdowns, and wide-spread testing were not associated with COVID-19 mortality per million people.”

That should have been obvious for a virus that holds little danger for prime working-age cohorts who are most impacted by economic lockdowns.

Like the moratoria on elective surgeries, lockdowns did more harm than good. Livelihoods disappeared, business were ruined, savings were destroyed, dreams were shattered, isolation set in, and it continues today. These kinds of problems are strongly associated with health troubles, family dysfunction, drug and alcohol abuse, and even suicide. It’s ironic that those charged with advising on matters pertaining to public health should focus exclusively on a single risk, recommending solutions that carry great risk themselves without a second thought. After all, the protocol in reviewing new treatments sets the first hurdle as patient safety, but apparently that didn’t apply in the case of shutdowns.

Even as efforts were made to reopen, faulty epidemiological models were used to predict calamitous outcomes. While case counts have risen in many states in the U.S. in June and July, deaths remain far below model predictions and far below deaths recorded during the spring in the northeast.

One last note: I almost titled this post “Attack of the Killer Morons”, but as a concession to what is surely a vain hope, I decided not to alienate certain readers right from the start.
