Science: opening schools without masks stops a coronaplague (data from Florida)

Inspired by the official coronascience that I’ve seen in the last 1.5 years, here is an analysis that follows the same logic and methodology….

Florida was suffering from a terrible coronaplague, leading to an exponential rise in hospitalizations of patients tagged with COVID-19, a tweet from the Florida Hospital Association on August 23, 2021:

As a way of fighting this wave of contagious death, public health officials wisely decided to reopen schools on the usual schedule, with the last school district opening on August 23, 2021 (calendar). Mixing students from different households in the same room, oftentimes without masks (due to a governor’s order that parents retain the ultimate decision regarding whether their children would wear masks 7 hours/day), diluted the coronavirus so as to render it harmless. Same chart from the same source, today:

The red curve that was rising inexorably toward infinity is now trending down, having peaked right around the time that schools throughout Florida were back in session.

Because coronanumbers don’t move without government action (see Thomas Aquinas regarding the Prime Mover and First Cause), we can be confident that it was the reopened mask-optional (depending on county) schools that caused the decline in hospitalizations. Thus, it is fair to say that #Science proves that unmasked children in schools, or at least tightly packed children in indoor classrooms (in the counties that defied the governor), are the key to ending an exponential coronaplague.

(Separately, while on a Zoom call with a group of MIT alumni a couple of nights ago, I asked the assembled group whether hospitalizations in Florida were trending up or trending down. All of the folks on the call, based on what they’d read in the media and heard on NPR, believed that COVID-19-tagged hospitalizations in Florida were trending up.)

(On a more serious note, deaths tend to lag hospitalization and therefore there are still quite a few people dying from what seems likely to be an annual summer COVID-19 wave in Florida. The cumulative death rate remains lower than in many states, but it is still painful to confront the fact that we humans cannot escape a determined virus.)

A little more support for my ventilation system upgrade idea

Build downdraft paint booths for K-12 schools? (July 2020, here on this blog):

The technology for downdraft paint booths is highly advanced … Why not a system for schools in which (a) each classroom has its own HVAC system, (b) there are 8-12 outlets in the ceiling, and (c) there are 8-12 exhaust outlets in the floor? For maximum safety, the system would have no recirculation.

More than a year later, in Atlantic, “The Plan to Stop Every Respiratory Virus at Once” (9/7/2021):

The original dogma, you might remember, was that the novel coronavirus spread like the flu, through droplets that quickly fell out of the air.

A virus that lingers in the air is an uncomfortable and inconvenient revelation. Scientists who had pushed the WHO to recognize airborne transmission of COVID-19 last year told me they were baffled by the resistance they encountered, but they could see why their ideas were unwelcome. In those early days when masks were scarce, admitting that a virus was airborne meant admitting that our antivirus measures were not very effective. “We want to feel we’re in control. If something is transmitted through your contaminated hands touching your face, you control that,” Noakes said. “But if something’s transmitted through breathing the same air, that is very, very hard for an individual to manage.”

The WHO took until July 2020 to acknowledge that the coronavirus could spread through aerosols in the air. Even now, Morawska says, many public-health guidelines are stuck in a pre-airborne world. Where she lives in Australia, people are wearing face masks to walk down the street and then taking them off as soon as they sit down at restaurants, which are operating at full capacity. It’s like some kind of medieval ritual, she says, with no regard for how the virus actually spreads. In the restaurants, “there’s no ventilation,” she adds, which she knows because she’s the type of scientist who takes an air-quality meter to the restaurant.

(See “Australia has almost eliminated the coronavirus — by putting faith in science” (Washington Post, 11/5/2020)_

I guess Professor Morawska wouldn’t like the simplest science-based way to get schools back to normal operations:

(some responses to the above:

  • “If they hold classes in a Walmart then schools can stay open”
  • “The hardest part of 14 days to flatten the curve is the first 18 months.”
  • “Possibly have the teacher come to their table to collect homework , so they can ask “menu ” questions….”

; Why is Kimberly’s idea “science-based”? The orders from governors that have reshaped U.S. society are purportedly science-based, including orders that restaurants can reopen at up to full capacity so long as masks are worn between the front door and the table. Therefore, by transitivity, Kimberly’s proposal for schools is equally science-based.)

If we have $trillions to spend fighting COVID-19, which we apparently do (though it is unclear why we wouldn’t instead spend the money on CO2 vacuums to deal with what our leading intellectual has called a “code red” threat to all of humanity from climate change), why wouldn’t we invest in ventilation?

Intersection of aviation and coronapanic: the flying COVID-19 testing lab

From a flight planning service (for Gulfstreams and similar jets):

As mentioned last week and in yesterday’s webinar, we now have a program to help you eliminate the wasted time and risks associated with securing pre-arrival COVID tests on international missions – by getting your N-registered aircraft certified as a mobile testing center.

You administer the tests yourself, safely and discretely onboard your own aircraft. Our lab partner … remotely analyzes the results and issues you a digital COVID test report – accepted in over 150 countries.

This is a new service we’ve been slowly scaling up over the past several months, and it’s proved to be a VERY EFFECTIVE alternate to trying to coordinate COVID testing abroad.

A reminder that the elites who order the various restrictions on crossing borders don’t necessarily have to scramble to meet those restrictions when they themselves feel like traveling…

This Quik GT-450 is perfect for reassuring passengers that a Cirrus, Piper, or Cessna is comparatively safe!

Wave of death among the elderly bankrupts Social Security

COVID-19 is the world’s greatest source of cognitive dissonance. We are informed by the CDC that roughly 640,000 Americans have died from COVID-19. The same agency tells us that deaths are concentrated among those who are old enough to be collecting Social Security:

Roughly 80 percent of the deaths are 65+.

We are informed by our brightest science-following minds in the media that COVID-19 has been killing people whose best years were ahead of them. Maybe the median age of a death in Maskachusetts was 82, but, absent coronavirus, those 82-year-olds being killed would have lived to 92 and, thus, collected an additional 10 more years of Social Security checks.

What happens to a financial enterprise when the obligation to send 10 years of month checks to hundreds of thousands of people goes away? “Social Security trust funds now projected to run out of money sooner than expected due to Covid, Treasury says” (CNBC, August 31, 2021):

The Social Security trust fund most Americans rely on for their retirement will run out of money in 12 years, one year sooner than expected, according to an annual government report.

The circumstances, which were exacerbated by the Covid pandemic, threaten to shrink retirement payments and increase health-care costs for Americans in old age sooner than expected.

So… our minds are supposed to simultaneously hold the following truths:

  1. COVID-19 kills mostly people old enough to be entitled to Social Security.
  2. The average old person killed by COVID-19 was healthy enough to live for at least another 5-10 years.
  3. Social Security will become insolvent as a result of not having to send checks to those killed by COVID-19.

Unless I am missing something obvious, the human mind is a wonderfully supple device!

Coronapanic is a huge boon for tenured faculty

A friend gets a guaranteed salary as a tenured professor at M.I.T. If he wants to drive away from his comfortable home, fight through the Boston traffic (back with a vengeance), and work all day in his office, he must comply with all of the procedures laid out at https://covidapps.mit.edu/covid-pass:

He prefers not to deal with this and therefore he has opted out of the system. What’s the consequence to him of failure to comply? He doesn’t have to commute and doesn’t have to work with students except in the rare instances when a student is able to pin him down and demand a Zoom meeting. Excluding infancy, he’s never worked less in his life.

Cambridge, Maskachusetts back under a mask order

From August 27, “City of Cambridge Issues Emergency Order Requiring Use of Face Masks in Indoor Public Places, Effective September 3, 2021”:

The City of Cambridge issued an emergency order requiring that face masks or coverings be worn in indoor public places. The order takes effect at 8:00 a.m. on Friday, September 3, 2021. It applies to everyone over the age of two years old, with exceptions in alignment with the Centers for Disease Control and Prevention and the Massachusetts Department of Public Health guidelines.

“I am grateful to everyone in Cambridge who has taken our public health guidance seriously, gotten vaccinated, and done their part to help protect themselves and our community,” said City Manager Louis A. DePasquale. “With the rapid rise of the Delta variant, we are issuing this mask order for indoor public places to reduce the spread of the virus and to protect those who live, work, learn, or visit our city. As we have done throughout the pandemic, we will take a data and science-informed approach to our pandemic response.”

“With schools reopening and COVID-19 cases increasing due to the highly infectious Delta variant, instituting this mask mandate for indoor public places is a critical measure to help minimize the spread of the virus,” said Mayor Sumbul Siddiqui.

It’s an emergency situation. COVID-19 is on a rapid (presumably exponential) rise. We have at our disposal a critical measure that we know will save lives. So… let’s wait a week before applying this critical measure!

Separately, my Uber driver in Cambridge on August 27 described what happens in the patchwork coronapanic landscape of Maskachusetts. “They closed the gyms in Boston, so thousands of people started coming to my gym in Quincy,” he said. “It was so packed that I couldn’t use any of the machines.”

Harvard, meanwhile, is #FollowingTheScience by closing the outdoor venue of Harvard Yard to walk-throughs… from 5 pm to 3 am (so everyone who wants to visit Harvard Yard must be sure to crowd in during the limited opening hours!).

In-person versus virtual learning effectiveness

Now that the school year is upon us, with periodic coronapanic shutdowns following positive PCR results, it seems like a good time to share the results from our MIT ground school course. We’ve taught this as an in-person class multiple times and once as a Zoom plus prerecorded lectures class (MIT Video Productions recorded the 2019 lectures). Considering only registered MIT students, scores on the FAA practice test were approximately 10 points lower (out of 100) after the virtual class compared to the in-person class.

(Of course, I don’t expect the demonstrated ineffectiveness of virtual instruction to convince the Shutdown Karens to reopen schools! #AbundanceOfCaution and #FollowTheScience)

Cancel my order for 200 million COVID-19 vaccine booster shots?

“Are We Jumping the Gun on COVID Boosters?” (MedPage Today, August 24, 2021):

Diminishing vaccine effectiveness supposedly makes the case for boosters. But there are two big questions here: First, what is current vaccine effectiveness? And second, what justifies boosters? Let’s consider these in turn.

We have to be honest, many vaccine effectiveness studies are poorly done. All studies compare the rate of getting a breakthrough infection among vaccinated people against the rate of infection in unvaccinated people. But there are some issues with this approach. First, as time goes on, more unvaccinated people have had and recovered from COVID-19 (and these individuals may be less likely to go on to get a shot). This means that their risk of getting COVID-19 a second time is far less than the typical unvaccinated person who has never been sick. Even if vaccines “work” as well as before, this factor alone will result in the appearance of diminishing vaccine effectiveness.

Second, the order of vaccination in all nations is non-random. The folks who got vaccinated first are often the oldest and most vulnerable people with frailty and senescent immune systems. Vaccine effectiveness after 6 months, 8 months, and 12 months increasingly compares older, frailer people who got vaccinated first against unvaccinated people. These older people may always have a slightly higher risk of breakthrough infections. This bias will also give the false appearance of diminishing vaccine effectiveness.

Humans are terrible at reasoning from statistics. Will our booster shot mania prove to be another example of this phenomenon?

Separately, I do wish someone would explain to me the mania for trying to coerce all of the unvaccinated into #AcceptingScience. We know that the vaccines we have don’t prevent infection or transmission. Our hospitals have plenty of capacity if we’re willing to do a little geographic load-balancing. Maybe an individual should care whether he/she/ze/they gets vaccinated. But why do his/her/zir/their neighbors care if he/she/ze/they gets vaccinated? We now know that the pandemic would not end even if 100 percent of humans were vaccinated.

Following the science in Australia

Department of “Surely coronavirus won’t be waiting for us after we emerge from our bunkers”. From Twitter:

Best headline: “Australia Almost Eliminated the Coronavirus by Putting Faith in Science” (Washington Post, November 5, 2020). From that article:

… unlike the Trump administration, which has criticized its primary infectious-disease adviser, Anthony S. Fauci, Hunt relied heavily on health experts from the start.

And for a time, it appeared Australia’s early success was imperiled, after lax security at hotels in Melbourne that were housing returned travelers led to a second outbreak in July. By August, more than 700 cases a day were diagnosed. It looked like Australia could lose control of the virus.

Almost all public life in Melbourne ended. After 111 days of lockdown, the number of average daily cases fell below five. On Oct. 28, state officials allowed residents to leave their homes for any reason.

Australia currently bans its citizens and residents from overseas travel, a decision that has been particularly tough on its 7.5 million immigrants.

Note that prevailing pandemic scientific wisdom prior to 2020 actually did support the idea that an isolated island with tight border controls might be able to delay or prevent infections via closing borders. See WHO guidance on pandemics then and now.

Readers: Will Australia and New Zealand be interesting case studies of what happens to countries where the plague arrives after nearly all of the old/vulnerable people are vaccinated?

Should Toyota bring back the Corona?

From the Henry Ford Museum:

“Toyota Corona” was a good name in 1966. Could it be considered a great name for the 2022 model year? The trim levels can be “Wild type” (or “Not Chinese”?), “Delta”, and “Lambda”.

Too morbid? Consider that the car in which JFK was assassinated was patched up and used by succeeding presidents for another 14 years.

The biggest tragedy for light aircraft is that Chrysler gave up on mass-producing turbine engines:

In 1930, Americans were sufficiently fond of each other that a family could live together in a 1,017-square-foot house:
