Who was right, the stupid programmer or the smart doctor?

A comment on “Power of the Media to Shape Coronaplague Beliefs” (June 29):

Brett Arron, MD

It is amazing that people are willing to dismiss the NYT reports while ignoring data evaluations by the experts in infectious diseases and epidemiology. New cases are a leading indicator of what is coming. Average onset of symptoms from exposure is 5.2 days ranging up to 10-14 days. It is another 10 days before hospitalization becomes necessary for about 20% of the population, It may be another few days before intubation and mechanical ventilation become necessary in about 2.5% of the infected population. Around 1.8% of the CoV19 patients progress from respiratory failure and develop failure of multiple organ systems and succumb to the infection 1-3 weeks after intubation.
Rather than trying to reason your way with an incomplete set of data and facts to an answer you would like, you would be best following expert advice. Wear mask, socially distance, minimize your exposure to crowds and encourage others to exercise exemplary citizenship and do the same.
BTW in some recent strains of the SARS2 CoV-19 virus spike S1 and S2 proteins have stable and more effective at transmitting the infection to cells.
Annual mortality in the US from the annual influenza seasons averages about 0.2%. US CoV-19 mortality rates are 10 times higher about 2%. With the recent trends to younger patients hopefully the mortality rate will start to fall.
Publishing half truths confuses the issues and distracts from our best responses. Sweden’s mortality rates are much higher than their neighbors. New Zealand clamped down hard initially and is now CoV-19 disease free.
Free speech has limits. It is illegal to scream fire in a movie theater. In this analogy, there is a fire in the theater and you and people like you are telling people it is okay to stay in your seats, just ignore the smoke and fire alarms, no one had died.
Herd immunity

My implicit prediction was that the downward/flat trend in deaths in the U.S. was likely to continue, despite the rising trend, starting in mid-June, of positive infection tests. This prediction was based on decades of experience… as a computer programmer. Dr. Brett Arron’s was based on actually knowing something.

It has now been roughly 8 weeks since the “new reported cases in the U.S.” started trending up. What are we seeing in the trend of “new reported deaths”?

———— everything above this line was written on June 29 ————-

Well… it looks like I owe Dr. Arron dinner! From NYT:

I surely wish that I had been right, partly because I love to be right but mostly because it is sad when a virus is able to kill people.

On June 29 there were roughly 40,000 cases (positive tests). Using Dr. Arron’s numbers, today would be roughly when we would expect those who tested positive on June 29 to die. The death rate is about 1,000 people per day. Dr. Arron said it would be 1.8 percent of those who tested positive, which works out to 720.

Other than admitting to being stupid, what is my explanation for being wrong? I have consistently underestimated the power of shutdown. Knowing that Americans, despite a “shutdown”, were continuing to meet in grocery stores, marijuana stores, liquor stores, on Tinder (record usage), etc., and having seen Americans wearing filthy bandanas underneath their noses as PPE, I did not believe that we were having an effect on viral transmission.

About two weeks after the post that kicked off this follow-up, I began to doubt my assumptions: “Coronaplague test data show that Florida successfully flattened the curve?” At least in Florida, everything worked the way that it was supposed to, according to the Church of Shutdown dogma, March edition. By sacrificing their children’s education, sacrificing their long-term mental and physical health, sacrificing development of work skills, and eliminating their social lives, Floridians actually did push their plague back by a couple of months. If Floridians did it, maybe people in a lot of other states “succeeded” as well. This is a Pyrrhic victory, of course, since the reward is simply prolonging the shutdown and the “war” that we’ve declared on the virus that we are almost certainly destined to lose. It is also not a “success” as defined by minimizing deaths, since the deaths from shutdown will far exceed any lives saved from slowing down Covid-19.

Could we have done anything differently if we had known that the decline in deaths was simply to a local minimum?

Wear masks more diligently? “The land with no face masks: Holland’s top scientists say there’s no solid evidence coverings work and warn they could even damage the fight against Covid-19” (Daily Mail, August 4)

Social distance more distantly? Well, people don’t bother once they’re masked. But, even if they did, what would be the point? Shift Covid-19 infections and deaths into October?

Minimize exposure to crowds, as Dr. Arron suggests? Young people have already given up on this, right? And old/vulnerable people are still in their bunkers.

What is the value of all of these data, aside from proving that Dr. Arron was right and I was wrong?

How is coronaplague down in Brazil? (and the rest of the IHME predictions)

Yesterday was August 4, 2020, the date on which the IMHE prophecies were supposed to be proven out. Let’s see how the reality compared to the June 10 prediction. In “Wicked Brazilians will take the place of the wicked Swedes in forecasts of doom?” (June 13) I noted that 5,248 Brazilians were forecast to be killed by Covid-19 yesterday.

What does WHO say about the actual number? It was 541 yesterday (August 4), 1,088 the day before (August 3), 1,212 on Sunday, August 2, 1,129 on Saturday, August 1., and 1,595 on July 31. Here’s my prediction in full:

My perspective is a “scientific” one. In other words, I will look at one or two data points and then extrapolate wildly. From the chart below, it looks like the non-virtuous Brazilians have, by dint of doing nothing, already “flattened the curve” to a large extent. So my first scientific observation (i.e., guess) is that the death rate on August 4, 2020 will be roughly the same as it is today. On the other hand, the virus has already killed a lot of the easiest-to-kill Brazilians. Therefore, the number should be a little lower. On the third hand, General Winter is fighting alongside the coronavirus in parts of Brazil. If the latter two factors cancel out, the number of deaths tagged to Covid-19 in Brazil on August 4 should be 1,274 (the number from yesterday’s WHO report).

Summary of the above: prediction of a plateau and therefore 1,274 deaths yesterday. So I’m off by more than 2X for the actual number, but the latest graph from IHME (a smoothed curve) does look vaguely plateau-esque, so perhaps I can claim victory on the shape?

Alex guessed 1,219 following YouYang Gu’s model. ajm did an interesting analysis starting from the Diamond Princess data and came up with 1,800. Henry went with IHME, but cut their 5,248 estimate by 50 percent due to his faith in the Sacrament of Masks. Sig came up with a technical analysis approach, as they say on Wall Street:

I think the pattern is quite clear here: after the peak it is a log-linear descent, with always the same slope. No need for science or following news… (Italy has a step there, they probably transitioned to a different counting method.) So, extrapolating for Brazil, which looks like being at the peak, to 130 days, which would be beginning of August in that case, and adjust for population, I arrive at 300 “daily new confirmed COVID-19 deaths”. Turns out SK already bet that, so I’ll go for 299.

The winner… SK! “My assumption it will fizzle our even more. My prediction is 300. Definitely less than 900.”

So… IHME was off by 10X (but maybe only 5X if we smooth the data?). I was off by 2.5X. When is it time to acknowledge that the virus is smarter than we are?

How about the rest of the IHME predictions? Back in April they were predicting 13,259 deaths for Sweden by August 4. The WHO figure from yesterday’s report is 5,744 (i.e., off by 2.5X). The same April post carried a prediction of 6,739 deaths for Massachusetts through August 4. That was without the assumption that the state would adopt universal masking. We did mask up and… the actual number was 8,436 (mass.gov).

In late March, IHME predicted 80,000 deaths for the U.S. through August 4, 2020, with a 95% confidence interval of 40,000 to 160,000. The WHO report number is 154,226. So they were off by almost 2X, but not so far off as to call their methodology into question.

If K-12 schools will be online-only, why not start right now?

“Most California Schools Unlikely To Open In Fall Under New State Rules” (NPR):

Most California schools may remain closed when the academic year begins in the fall, according to new state directives, with a majority of campuses likely having to shift to distance-learning instead.

The new requirements stipulate how and when schools may reopen for in-person learning when the academic school year begin. … Under the new rules, a county must also not be on a list of counties being monitored for rising coronavirus infections. Thirty-two of the states 58 counties currently don’t hit that benchmark. To open schools for in-person instruction, those counties would have to be off that list for 14 consecutive days, according to the directives.

The directives are on the heels of announcements that some of the state’s largest districts had already decided to enter the academic year with no in-person classes. Los Angeles, San Diego and San Francisco all recently said they planned online-only learning when students returned.

This makes sense for a population whose only goal in life is avoiding Covid-19 infection. But why wait for the fall? Given that students already missed a lot academically during what would have been the spring semester, wouldn’t it make sense for K-12 to start up right now for any student who wants to try to catch up? Supposedly, the schools and teachers that did a lame job with online education in June will be doing an awesome job in September. But why not start with the awesomeness tomorrow, for example?

Karen’s Mask Report from Maskachusetts

In early June I posted “Karen’s Mask Law Compliance Update (Boston to Minneapolis and back)” (this trip plus a trip to the local supermarket would now be illegal under the new Maskachusetts rules!). Here’s an update based on a rare day out and about.

When not filled with arguments about how to pay for the most expensive (per student) school ever to be constructed in the United States, our righteous suburb (rich in BLM and Rainbow flags, if not in people who identify as persons of color or members of the LGBTQIA+ community) is filled with arguments about the best approach to coronapanic. The latest furor concerns the lethal Covid-19-spreading properties of Canis familiaris. Touched someone else’s dog? Dig yourself a grave. A proposed solution is that our town will one day see reason and pass a leash law to reduce the chance of human-canine encounters.

Thus, it was with some trepidation that I took Mindy the Crippler for her first post-plague visit to the grooming salon. If our neighbors are right, the groomers should all be dead. Folks in the salon apparently did not get the memo regarding the hazards of touching dogs and, remarkably, have failed to die on schedule. While Mindy was having her spa treatment, I met a couple of friends for a rare indoor dining experience at a Panera-style restaurant (order at counter; food delivered to table). They have failed to adapt to coronaplague by augmenting the handful of outdoor tables and it was super hot outside so we ate indoors.

We’re in Month 5 of shutdown here and Month 3 of the universal mask law. Everyone seemed to be attempting to wear masks, but, just as the Swedish MD/PhDs predicted, once they were masked they made little attempt to keep a 6′ social distance. There were a fair number of masks-under-noses as well. We’re spending $trillions on things like $600/week handouts to people who became unemployed after the License Raj made it illegal to operate restaurants. But there doesn’t seem to be any money for adaptions that would contribute to long-run plague reduction (like my pet idea for schools). For example, cruise ships usually have handwashing sinks near the entrance to restaurants. Not this restaurant. If we believe the W.H.O. guidance on mask usage (early June 2020 edition of “science”!), the restaurant should have had a sink outside near the outdoor tables and an indoor sink that didn’t require going into a restroom. After all, masks are effective only when combined with handwashing, so we were told by W.H.O. But, in fact, there were no sinks for customers other than ones in the restrooms.

I took Senior Management’s car for a state inspection on the way back to the groomer. None of the guys at the gas station were wearing masks when working in the bay or outdoors, but put them on (without washing hands!) when going inside the shop to run credit cards with customers.

Mindy wasn’t quite ready, so it was necessary to kill time at Dunkin’ Donuts. The women behind the counter were both wearing masks… underneath their noses. Then the hardware store to buy three bottles of drain cleaner to address a slow kitchen sink. “Why do you need three bottles?” asked the partially masked woman in the store? “One thing I have learned from our government is that when something doesn’t work, keep repeating it over and over.” (The grease clog and a small leak in the elbow were eventually solved by a plumber for $370, further evidence that owning property in the U.S. is stupid, except for the exceptionally capable who can do everything themselves.)

A Sunday trip via Cirrus to Martha’s Vineyard (one of the few places to which Maskachusetts residents can legally travel to/from) showed that the island is all-in on masks (“Wear a Mask, Make a Difference” says the sign, contradicting the W.H.O.’s advice through early June and the MD/PhDs in Sweden):

Note the mask directives for boarding the ferry to Chappaquiddick. Perhaps if Ted Kennedy had worn a mask, American politics would have gone in a different direction! (my Cape Cod photos include historical photos of the inn where Teddy K stayed and the motel room where Mary Jo Kopechne stayed).

Two miles away…

I still wonder if having customers inside retail stores makes sense in a country where the only goal is avoiding COVID-19. As noted in “Train Americans to use masks the way that surgeons do or restructure the physical environment?”, why can’t stores go back to their 18th century roots: Customer enters spacious front part of shop and asks for item. Shopkeeper goes into jammed back part shelves to retrieve requested item. (tweak so that customer never goes into the store itself, but stays outside and transacts business over a counter)

We’re afraid of getting Covid-19 from surfaces, right? (hence the constant sanitizing) We’re also afraid of getting Covid-19 from sharing air. How can it make sense to put the entire country at risk by continuing to operate retail stores as they were configured in the pre-Covid-19 age?

Why hold elections in non-swing states?

A Facebook Mask Karen (his profile picture is at least 50 percent face covering) highlighted “Coronavirus creates election worker shortage ahead of November” (Politico): “Local election authorities typically rely on older volunteers, who are dropping out in higher numbers over coronavirus fears.”

This prompted me to wonder why we would have an election at all here in Maskachusetts. Most candidates will he running unopposed. For the remainder, the outcome is already known. Why have people gather to infect each other when there is nothing to be decided?

Readers: What is the point of a November election in one-party states such as California, New York, et al.? If #BecauseEmergency is sufficient reason to cancel what used to be Constitution rights that had some value (e.g., the rights for young healthy people to receive an education, assemble and socialize, go to work, etc.), why isn’t #BecauseEmergency sufficient reason to cancel a valueless right (to vote in a non-primary election in a non-swing state)?

If we insist on some kind of count, we could do it safely with a drive-by inspection of lawn signs. Every “Hate Has No Home Here” sign can be counted as a vote fore Joe Biden:

Anyone who has the temerity to place a Donald Trump on a lawn in our town will typically find that the neighbors correct the mistake within a few days. Votes for Trump cannot therefore be via a sign with the hated dictator’s name on it. Maybe a yard sign like this would be sufficiently subtle?

Security Theater intersection with Coronapanic Theater: illegal to fly over an empty stadium

The Boston Red Sox are playing in Fenway Park again, but fans aren’t allowed into the stadium. After the jihad of 9/11, the major league sports teams were able to realize their dream of blocking banner-towing airplanes from flying over stadiums. The banner-towers were competing with the teams for in-stadium advertising dollars. The dream of eliminating this competition had been out of reach for decades due to a legal/FAA doctrine that airspace belongs to the public and therefore the teams couldn’t own the airspace above their stadiums.

After 9/11, the teams got Congress to lean on the FAA to put in a “temporary flight restriction” (the temporary restriction will soon turn 20 years of age!) forbidding all aircraft from overflying within 3 nautical miles and 3,000′ (of course, a helicopter 3 miles away and at a normal helicopter cruising altitude would not really be an “overflight” since it wouldn’t be visible from the stadium). This is in the name of “security”, though it is unclear what the practical effect could be on security since the typical terrorist is already violating a variety of regulations and laws by carrying out a terrorist act.

Given that the stadiums are 99 percent empty, has the rule been relaxed? No! So we’re not allowed to do our helicopter tours over Boston (we don’t need to fly over Fenway Park, but it is quite close to the center of the city, so a Fenway TFR makes the tour essentially impossible). Families heading to Cape Cod in little planes won’t be able to take the conventional shortcut through Boston and over Logan Airport.

This was sold as a way to keep a determined jihadi from wiping out 30,000+ people with a Cessna 172 or similar (though, as noted above, it was unclear how it ever could have worked to achieve that end). But now it is being applied to ensuring security for a handful of baseball players who are all alone in the stadium.

The league, armed to the teeth with power and privilege, access to testing, cash flow, precision data collection, and high-powered, lower-risk athletes playing outdoors, was supposed to prevail. … baseball and other sports will help get us there by aggressively gathering information about the risks we are all facing. In the end, this will be prove to be more valuable than anything normalcy can provide. We are playing to survive.” (i.e., we will learn more from Major League Baseball than from all of the MD/PhDs working for the Swedish government!)

Fanny pack sales will get a boost from coronapanic?

Americans have spent months at home, lounging in sweats and stretchy shorts while watching television and/or playing with their phones. Our heroes get off the sofa only for periodic dives into the fridge for waist-expanding calories.

Will we be able to tolerate the discomfort of ordinary pants and belts ever again? If not, how will we carry wallets, keys, and phones? Running pants aren’t adapted for this application. Enter… the fanny pack!

Build downdraft paint booths for K-12 schools?

Unionized American school teachers refuse to work unless they can be guaranteed not to get coronaplague from the students. Words are not going to soothe these concerned souls. “School closures ‘a mistake’ as no teachers infected in classroom” (Times of London, July 22):

Scientists are yet to find a single confirmed case of a teacher catching coronavirus from a pupil anywhere in the world, a leading epidemiologist has said.

Mark Woolhouse, an infectious disease epidemiologist at Edinburgh University, offered reassurance to staff preparing for the full reopening of schools next month.

I predict that this won’t result in a single American school opening up for business as usual. Zero cases is one case too many!

Americans apparently did not like my previous pet idea: “Plague-proof Florida and Texas with shaded outdoor classrooms?”

Thus, it is time for another pet idea! This one comes from the world of aircraft and automobile painting: pull student exhaust air down through the classroom floor. The technology for downdraft paint booths is highly advanced (example). They have been built large enough to paint a Gulfstream. Below are a couple of photos from West Star Aviation, which paints some very big airplanes indeed. At right is your humble author next to some of the air filters, against which coronavirus would stand no chance.

Presumably the airflow wouldn’t have to be as powerful for a classroom as for a paint booth. Air conditioning systems have been implicated in spreading coronaplague among adults, right? 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.

(Separately, as long as we’re on the topic of aircraft paint, at West Star I noticed that all of the people working in the 100-degree hangars sanding the paint off jets seemed to identify as “men” while there were folks appearing to identify as “women” working in air-conditioned offices and comfortably sitting in chairs.)

Covid-19 will go away if we just keep our schools closed

Good news from the Department of Correlation DOES Equal Causation: if we keep our schools closed, coronavirus will go away and leave us alone. From the maximally prestigious JAMA: “Association Between Statewide School Closure and COVID-19 Incidence and Mortality in the US”

Some excerpts:

All 50 states closed schools between March 13, 2020, and March 23, 2020.

The absolute effects associated with school closure during the 26-day period after school closure (days 17-42), which were calculated using model estimates with the assumption of linear growth, yielded 638.7 cases per 100 000 that would have occurred if schools had remained open (Table 3). Compared with the 214.8 cases per 100 000 estimated from the school closure model, the absolute difference associated with school closure was 423.9 (95% CI, 375.0 to 463.7) cases per 100 000.

In March 2020, states enacted multiple nonpharmaceutical interventions, including closing schools, nonessential businesses, and restaurants and bars, and prohibiting large gatherings, to curb SARS-CoV-2 spread and prevent death. Completely isolating the effects of any single nonpharmaceutical intervention is impossible because recommendations for increased handwashing, cleaning, and wearing of masks evolved simultaneously. Measured COVID-19 incidence also was affected by testing availability, which was limited early in the pandemic and varied nationally.

The authors reject the “Flatten the Curve” dogma as it was explained to us back in March. Infections are not merely delayed. They are prevented. The shutdown was “to curb SARS-CoV-2 spread and prevent death” and “school closure may be effective in curbing SARS-CoV-2 spread and preventing deaths during future outbreaks.”

Should we be more afraid of touching a dog with coronaplague in his/her/zir/their fur (an often-voiced concern of neighbors here in the Boston area) or a child?

Studies have documented lower attack rates for children, and children comprise a small proportion of documented infections. Children may be less susceptible to SARS-CoV-2 infection; however, studies have documented viral shedding in asymptomatic children.

I would like to re-title the paper, though, even if I don’t feel distinguished enough to criticize the statistical methods employed.

Visual artists will switch to outdoor sculpture due to plague?

With art museums closed or compromised (regulated pre-arranged visit times, masks, etc.) and art galleries damaged by the destruction of American retail, will visual artists switch to outdoor sculpture?

If most people with money flee the cities to suburban or country estates, and then spend a lot of time imprisoned in their yards, that’s a big market for attractive sculpture, right?
