Dear friends in British Columbia🇨🇦—you are a beautiful place & I’ve had family live/study there. You handled pandemic well last year. But BC is not doing well right now—it has the highest R currently in 🇨🇦—1.54 (figure from @DFisman) & the highest new cases per capita. Stay safe.
2) I love @brittlestar.
3) I’m worried about other places in Canada too...
4) Montreal has a #B117 driven outbreak too.

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. 🧵

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).

Ted Cruz & Josh Hawley’s former law professor (who taught them both) went off on his former students...

‘I was thoroughly disgusted with the reprehensible behavior and the reprehensible language of both of my former students’ 🔥

Best video of the night.
2) Ted Cruz... does not seem very smart.
3) let me rephrase — Cruz is still smart. But I feel he is tone deaf and lacks emotional & social IQ. It would explain his super weird Cancun decision too. I wish some psychologist can diagnose what he has. @BandyXLee1?

The CDC just sent a response why they haven’t emphasized airborne. They confuse aerosol & droplets.

➡️3 modes of #COVID19 transmission:

1. Touch
2. Spray droplets
3. Inhalation

*But even at close range, exposure is more likely by inhalation than spray*—see 🧵 by @Don_Milton.
2) The CDC response is in response to @briancolder’s request for information.
3) the gist is that CDC refuses to act and make airborne precautions official guidelines until they can see proof airborne is a greater threat than droplets by framing it as wanting to see hard proof of “proportion of infections”—which is *absurd* from precautionary principle.
