Madness—NCAA will bring fans back to the stadiums for the men’s and women’s NCAA basketball 🏀 tournament—albeit at lower capacity. But having thousands of fans arrive from all over the country creates #COVID19 super-spreader risks—as well as bars/hotels. nytimes.com/2021/02/19/spo…
2) The 68-team men’s tournament, which begins on March 18, will be played in Indianapolis before crowds of up to 25 percent capacity at sites ranging from the quaint 9,100-seat Hinkle Fieldhouse to Lucas Oil Fieldhouse, which holds up to 70,000 fans.
3) The 64-team women’s tournament, which begins on March 21, will allow up to 17 percent capacity from the regional semifinals through the championship final in San Antonio. Those games will be played at the Alamodome, which has a 31,900-seat capacity for basketball.
4) Unlike baseball ⚾️ or football 🏈 which are played outdoors, indoor basketball is much different risk levels. Even if masked, what is ventilation rates, air disinfection rates? Masks are not enough for long periods indoors with high density of people.
5) Here is my detailed ventilation thread 🧵 about why we need air cleanings and ventilation.
COVID hidden in lung 🫁 transplant—transplant recipient tragically dies after receiving donor lungs, unbeknownst infected with #COVID19. The surgeon also contracted same #SARSCoV2—both infected from the dead donor’s lung, verified from genetic sequencing.🧵nbcnews.com/health/health-…
2) “Doctors say a woman in Michigan contracted Covid-19 and died last fall two months after receiving a tainted double-lung transplant from a donor who turned out to harbor the virus that causes the disease — despite showing no signs of illness and initially testing negative.”
3) “Officials at the University of Michigan Medical School suggested it may be the first proven case of #COVID19 in U.S. in which virus was transmitted via an organ transplant. A surgeon who handled the donor lungs was also infected with the virus & fell ill but later recovered.”
AIR DISINFECTION—To reduce airborne #SARSCoV2 risk, new study finds HEPA cleaners, with total air exchange rate of 5.7 ACH/hour, after 2 hours in closed room with a highly infective person—the inhaled dose is 6x reduced!
2) In times when classes were conducted with windows and door closed, the aerosol concentration was reduced by more than 90% within less than 30 minutes when running the purifiers (air exchange rate 5.5 /hour)—and decreased by more than 95% within 37 minutes.
3) A **halving of the particle concentration was reached in 10.0, 7.0 or 5.4 minutes** (green, black and red lines, respectively), depending on the total flow of the purifiers.
The blue line shows a typical slow decrease when no purifiers were used.
3) Meanwhile US has lost a full year of life expectancy in the first half of 2020 alone. 2.7 years of life lost for black Americans. 1.9 years lost for Hispanic Americans. 0.8 lost for whites.
2) What’s more— @AOC actually personally came to Texas and helped on the front lines, whenever she didn’t have to (she’s not even elected by Texas).
3) And let’s remember the moral rot at the heart of all is is that Texas leader consciously neglected to winterize and purposefully deregulated and avoided federal regulations.
3) Chasing natural infection herd was part of Sweden’s strategy from the beginning. And they told themselves sweet little lies from the beginning. Here it is a little annotated history timeline...
3) These numbers are quite low. Shockingly low. Granted a lot of these 3,953 middle and high school students with in person classes are schools in states with looser or no mask mandates. But I’m most worried about mask wearing with such mediocre to low prevalence.
