> It appears that the virus travels through the air, so whenever possible, it’s important to avoid crowds of people or indoor spaces with shared air. The virus is about the same size as the particles in cigarette smoke (though it would usually be part of a larger droplet), so I find it helpful to imagine a smoker exhaling smoke, and what it would take to avoid inhaling too much of that second-hand smoke.
I just got back from a bike ride and I went through an area where a lot of homeless hang out. I could strongly smell urine and smoke while I was waiting at a stop light under a bridge. Do I need to be concerned that I just exposed myself?
The virus can travel through droplets and other large particles, so you definitely have to watch out for people sneezing etc. around you. There isn't any consensus, however, for whether it is airborne or not, i.e. whether it can be in regular exhaled air. Of course you should take precautions regardless.
