7 feet or 12 feet is *NOT* the main risk mitigation issue. The main issue is AIRBORNE transmission if someone in the debate hall is a asymptomatic carrier—thus how much fresh air ventilation, >=6 air exchanges, available HEPA/MERV13+ filtration? #COVID19 https://www.cnn.com/2020/10/02/politics/vp-debate-coronavirus/index.html

2) Again, 6 feet rule not enough indoors

3) How is aerosol different from large droplets? aerosol study indicates that coronavirus is persistent and stable up to 16 hours in stagnant air. Typical air exchange every 20 min to 4 hrs, depending on ventilation. #COVID19

4) Masks are of course MOST critical of course. Though unlikely TV debaters won’t be using masks, but it honestly would make a huge difference if they did debate with masks on. See under laser light.

5) Hope people aren’t tired of these aerosol videos, but so important to rub in how important ventilation is. Japanese assumed aerosol risks of #COVID19 from the beginning. This video explains what is needed to clear a room with fresh air. #COVID19
