A lot of people still think about Covid as a wash your hands and socially distance kind of thing.

Chances of getting Covid from touching something is near zero and we're far more likely to catch it from someone we can't see because it can stay in the air for a long time, drift long distances, and remain potent long after a contagious person is gone (as much as 2 hours).

This is why improving ventilation is one of the most important things you can do to reduce risks of infection for yourself and people around you. With good air flow, an infectious person is less dangerous. Infected air is diluted and can't linger to keep infecting.

I took a variety of CO2 readings to estimate indoor air quality. Based on these readings, places I wouldn't want to be unmasked would be: house gatherings, offices, meeting rooms, conventions, public transit, a plane, funerals.

Places that may not be as risky as originally believed are: supermarkets, pharmacies, and restaurants.

@sysop408 Wash your hands anyway. Wash them early and often. The flu can be spread by surface contamination, and the world has more antibiotic resistant bacteria any ever. WASH YOUR HANDS FOR REAL, AND mask plus go for as much ventilation and air filtering as possible.

@BegoniaArizona By all means, do wash your hands, but just don't think that's how you're going to dodge getting Covid and yes mask as often as you can.

I don't push that because that's going to lose a lot of people. This is about pushing harm reduction and convincing people to improve ventilation is the most effective harm reduction method we have.

@sysop408 I work with both babies and with the elderly. Hand washing definitely saves lives; same with those who are immune compromised. Also, good ventilation is essential for health and minimizing Covid spread, agreed. You are so right!
