📍NOTA BENE—Don’t be deceived if you see nobody in a room. CO2 levels can still be high if room is poorly ventilated. Remember #SARSCoV2 aerosols can stay airborne from 20 min-16 hours in stagnant air. CO2 is the easiest metric to tell you it’s stagnant. #COVIDisAirborne #COVID19

2) This is especially also important in public bathrooms. You may think you’re alone but toilet 🚽 plumes are real. And toilet flushing are well known powerful aerosolization devices. And in th US, most public bathrooms don’t have toilet lids (aka toilet mask).

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

5) Yes, toilet plumes are real...

Flushing the Toilet May Fling Coronavirus Aerosols All Over

A new study shows how turbulence from a toilet bowl can create large plume that is potentially infectious to a bathroom’s next visitor.

6) Now that aerosol transmission of the coronavirus is established, we need to disperse aerosols quickly. Key is ventilation. 🇯🇵 assumed it was airborne from the beginning. Here is how to ventilate your school classrooms if unable to open window. #COVID19

7) More fecal aerosol toilet plume studies. washingtonpost.com/health/2020/06…
