There might be a colony of the virus on a surface, or in a few air-born droplets hanging out in the room. If your device didn't happen to sample those particular droplets or surfaces, you'd never know they were there.
- bradknowles 5y agoTrue, there are multiple methods for transmitting the viral particles in question, but contact transmission would require that you actually come into contact with the surface in question. I don’t know what the exact numbers are, but I believe that contact transmission is considered fairly rare for COVID. Moreover, having a partial solution to the problem is better than no solution at all.
