In these two articles (see links below) from the Atlantic, it’s pointed out that the COVID-19 infection is passed person to person mainly in airborne respiratory droplets. Outdoors is much safer than indoors. Surfaces (elevator buttons for example) do not appear to play a significant role. Activities like choir singing, indoor restaurants, call centers, and areas with low indoor ventilation all have been shown to increase risk. Obsessive cleaning may be “hygiene theater” producing “prevention fatigue.” Best evidence so far for prevention: mask up, continue to social distance, avoid prolonged stays with others in indoor spaces, and hand washing. The longer and closer the contact to an infected person, the greater the risk.
