⚠️Global case decline has reversed—#COVID19 is once again surging overall worldwide / no longer dropping. Especially in Europe where the more contagious #B117 variant is driving faster spread & helping launch another wave (as I’ve been shouting at the rooftops for last month). 🧵
2) Denmark is the perfect example — they knew it was coming with the #B117 dominance. They knew it was inevitable but nobody listened.
3) Denmark CDC warned us in January to not be complacent
4) Others have also tried to warn. Models by @GosiaGasperoPhD also warned of the impending menace of #B117 in triggering a new wave if it replaces the old slower common type.
5) With #B117 more contagious, what used to work to contain the old may not work anymore. Denmark has been having trouble now too once #B117 has surpassed old strain and become dominant. Vaccine rollout not fast enough in most places.
6) #B117 in Florida is one of my biggest worries. It will likely dominate by late March across the US, but possibly sooner in Florida

FIRED FOR DEMANDING AIRBORNE & VENTILATION SAFETY—I want to say kudos to bravery of @BenBonnema for speaking out for safety of workers and shoppers at Trader Joe’s. Corporate HQ didn’t like him speaking out on #COVID19 safety—fired him instead. Disgusting. ibtimes.com/trader-joes-un…
2) here was Ben’s letter that set off his firing. He only advocated what the CDC recommended for schools just yesterday evening.
3) Meanwhile, the CDC just came out strongly in favor of indoor air quality in schools! See detailed🧵

BREAKING—A new hope—3rd vaccine is now approved. FDA has emergency authorized Johnson & Johnson’s single-shot #COVID19 vaccine. US now adds 100 million doses by June, on top of 600 mil Pfizer/Moderna 2-dose vaccines. ➡️US now has enough to donate too. 🧵
nytimes.com/2021/02/27/hea… Image
2) Besides 100 mil for the US, the J&J vaccine has been ordered by UK 🇬🇧 (30mil), EU (200 mil), Canada 🇨🇦 (38 mil) and 500 mil by COVAX nations. Image
3) While overall efficacy was 66% (pretty good), excluding South Africa and Brazil where variants dominate, US trial efficacy was 72%. Severe illness efficacy was 85%, and efficacy against mortality was 100% so far during followup. This is key. bbc.co.uk/news/world-us-…

HUGE—CDC just released NEW indoor air guidance for schools & #COVID19! Now emphasize: “Opening windows, using portable air cleaners, improving building-wide filtration are ways to increase ventilation in school or child care program.” Good, but caveats:🧵 cdc.gov/coronavirus/20… Image
2) “Bring in as much outdoor air as possible.
If safe to do so, open windows and doors. Even just cracking open a window or door helps increase outdoor airflow, which helps reduce the potential concentration of virus particles in the air.” Image
3) “Use child-safe fans to increase the effectiveness of open windows. Safely secure fans in a window to blow potentially contaminated air out and pull new air in through other open windows/doors.

VENTILATION IS CRITICAL—The CDC should be doing more to guide and encourage improved air circulation in schools to help prevent the spread of #COVID19. CDC has not paid anywhere near enough attention to the role ventilation, and air disinfection. 🧵

cnn.com/2021/02/25/hea… Image
2) “Schools will need to spend time and money improving airflow using HVAC systems, stand-alone HEPA air filtering systems or even just by opening windows if students, teachers and staff are to return safely to in-school learning in the fall, the experts say.”
3) “The state of ventilation in schools in the United States right now is woefully inadequate," Richard Corsi, dean of the College of Engineering and Computer Science at Portland State University, told a forum hosted by JHU Bloomberg School of Public Health this week.

JUST IN—Tennessee is investigating vaccine wastage and potentially improper temperature storage of thousands (possibly tens of thousands) of #COVID19 vaccines past their shelf-life outside freezers. They had improper record keeping in Shelby County. Damn🧵 tn.gov/health/news/20… Image
2) State investigators cannot verify that all the thousands of vaccines were even refrigerated or frozen properly!!!
3) Apparently TN dept of health found that Shelby County was inappropriately stockpiling vaccines and throttling them instead of giving them out to high risk eligible patients. This is super weird. Image

Here in Washington DC, entire roads & lanes completely change direction mid-day... via a giant road machine that literally “eats” the concrete barriers and “spits” them out the other end.

In other words, perfect reflecting of the meat grinding life in America’s capital. 🇺🇸
2) To be clear, this isn’t some HOV segregated lane with extra wide berth. It’s literally one LEFT lane that directly BECOMES the new left lane of the oncoming direction. And the machine COMES directly at you! ImageImage
3) Also at rush hour, ENTIRE ROADS goes from being ONE WAY one direction to ONEWAY other... and even a whole damn bridge (with no other bridge option for miles and miles on either side).
