Why is @CDC new guidance on droplet/aerosol transmission a big deal and not just schematics? Think about tornadoes and hurricanes. Both are swirling masses of air that can be extremely dangerous. Both have warning systems. Both have proven harm reduction strategies. 1/5

For tornadoes we can take shelter in basements, for hurricanes we can evacuate and avoid flood prone areas. However if we are only told to worry about tornadoes in a storm, we won't take any action to save ourselves from the flooding of a hurricane. 2/5

This weekend @CDC issues a warning that we should be worried about the massive hurricane and take all necessary steps to mitigate the damage (masks, portable air cleaners filters, ventilation), but keep an watch out for any tornadoes (masks, spacing, cleaning) it spawns. 3/5

The important point is not the details of droplet/aerosol debate. It is that schools, stores, municipalities now can point to @CDC guidance to justify implementation of aerosol risk reduction actions, rather than to point to the @CDC to prevent aerosol reduction actions. 4/5

The hurricane warning has been issued. The next challenge is to educate the public on layered risk reduction actions that address the challenges of this aerosol hurricane. We can do this. Mask up inside. 5/5

Sorry, this was a draft thread. My bad. Turns out it is sunny out.
