FOCUS ON AIRBORNE, *not* surfaces. Scientists increasingly say that there is little to no evidence that contaminated surfaces can spread the virus. Health officials are being urged to focus instead on improving ventilation and filtration of indoor air.…
2) “A lot of time, energy and money is being wasted on surface disinfection and, more importantly, diverting attention and resources away from preventing airborne transmission”
3) “People are removing masks for lunch or when they get back to their cubicle because they assume their cubicle is their private space... But remember: The air you’re breathing in is basically communal.”
4) Listen to airborne experts like @kprather88.
5) Here is a master thread on why and how we know it’s airborne in aerosol form. Dr Prather was the one who warned Fauci on airborne transmission.
6) How is aerosol different from large droplets? Aerosol stays in the air. Typical air exchange every 20 min to 4 hrs, depending on ventilation. #COVID19
7) Mask and airborne compilation science summary video
8) VENTILATION is key. Both ventilation and masks needed to reduce risk indoors. But most buildings not ventilated well enough.

9) Key is ventilation. Japan assumed it was airborne from the very beginning. Hence their mask culture and focus on air flow. Here is how to best ventilate with just doors and windows. #COVID19
10) again, who do we have to thank for alerting Fauci on airborne? Kim Prather. Without her, we might not even have airborne guidance yet.

📍Reinfection worry re-emerging—another documented reinfection case - this time of a 21 year old women in South Korea. There are now officially 26 confirmed reinfections and 1 death, and 572 suspected reinfections of #COVID19. Infection is rare but not blue moon rate it seems.
2) The best centralized tracking source for reinfections of #COVID19 worldwide is @BNODesk’s REINFECTION TRACKER page.… Image
3) notably, it was two different virus strains. “The spike protein D614G substitution that defines the clade “G” emerged in reinfection, while mutations that characterize the clade “V” (ie, nsp6 L37F and ORF3a G251V) were present at initial infection.”…

BREAKING—FDA has granted emergency use authorization for @Regeneron’s monoclonal antibody cocktail REGEN-COV2 (Casirivimab and imdevimab), the same drug given to Trump when he was infected with #COVID19. Only for mild/moderate cases—not hospitalized. 🧵… Image
2) There are a lot of rules and FDA stipulations for REGEN-COV2 cocktail use though— cannot be used if patient on oxygen (Trump was) or hospitalized. Children must be 12 or old and weigh 40 kg or more.… Image
3) And it’s only for those mild/moderate with “high risk of progressing to severe #COVID19”—and thus need to be defined carefully what constitutes high risk of progressing: Image

2) It didn’t have to be this way if Trump WH and many state leaders acted faster: because we know containment works.
3) and we know mask mandates work too. New CDC report

⚠️Crap crap—El Paso morgue crisis escalated fast. First it was jail inmates moving deceased bodies for $2/hour, then $27/hour job posting, and now Texas National Guard summoned up to help at El Paso’s overflowing morgue.
2) Earlier El Paso morgue attendant job posting for $27/hour.
3) All the while, TX Senator Ted Cruz called Senator Brown a "complete ass" for asking a maskless Dan Sullivan (R) to wear his mask in the Senate. Since then, 87-year-old Chuck Grassley (R) & Rick Scott (R) have both tested positive for #COVID19 & El Paso having morgue crisis.

📍DEVASTATING ANIMATION—Containment measures 🆚 #COVID19 case surges and hospitalizations 🏥 by state.

Hospitals are now almost full nationwide and ICU beds will soon run out. Please don’t do anything to risk spreading the virus over the holidays. Please stay safe everyone. 🙏
2) New York mostly kept it under control up until very recently.
3) As reminder — CDC report reminds you that masks work.
