AIRBORNE BUT NO GUIDANCE??? The CDC still not fully willing to update #COVID19 guidance for more premium masks & ventilation—even though prominent scientists, including members of Biden’s former COVID Task Force, sent a letter of concerns to CDC & Fauci.🧵

2) The stern letter by very prominent scientists. They argue that because #SARSCoV2 is very airborne and infectious, the CDC must advise & provide the public, especially high risk front line workers (not just healthcare workers), should have premium masks like N95 KN95 FFP2 etc.

3) moreover, they argue proper scientific distinction must be made between aerosols that stay in the air and respiratory droplets (that drop and fall to the ground in 6 feet due to gravity). drive.google.com/file/d/1O5zd_J…

4) And they lay out that the Us also needs to ramp up production of premium masks.

5) And they called for WH to “Use the Defense Production Act to ramp up production of N95 FFRs (particularly models already certified and in wide use), elastomeric respirators, powered air purifying respirators”

6) And they emphasize the need to focus on ventilation! And respiratory protection FOR ALL WORKERS.

7) CDC’s response was pretty tepid and generic. And didn’t answer anything or say what they will do next.

8) We desperately need to make classrooms safe. Here is a detailed 🧵 how to ventilate and calculate air refresh.

9) air disinfection devices help stop #COVID19. Period. They work. We need to get real and use them to make schools safe.
