CDC TOO LOW—I told @mehdirhasan that CDC Director’s 450k death projection is an under projection of #COVID19 deaths. We could likely hit 500k+ by end of Feb. And we already hit 3100 deaths yesterday. And they are real—all the body bags don’t lie.

Mask + Ventilate + Filter + UV. https://twitter.com/mehdihasanshow/status/1337565331041226752

2) Mask at all times. Check CO2 monitors for air circulation. Ventilate indoors. Use HEPA filter. Use UV for schools and major office buildings.

3) Don’t use UV without professional technicians and products. Don’t use with people around or in direct exposure of people. But they do work - and often used in hospitals.

4) VENTILATION is key. Both ventilation and masks needed to reduce risk indoors. But most buildings not ventilated well enough.

5) Masks and aerosols. Masks are *CRITICAL* for stopping droplets and aerosols.

6) Mask and airborne science compilation

7) we know public health measures work to prevent infections and hospitalizations. But so many leaders ignored the science. That is the greatest tragedy of #COVID19 pandemic.

8) 5 minutes of airborne aerosol exposure enough, even if 20 ft or more away from an infected person indoors. https://twitter.com/drericding/status/1337391610657710081
