You can't really give a time like that. People with detectable levels of covid might have anywhere between 100 and 10^14 viral copies/cc in fluid samples taken from them depending on their immune system and stage of progression. Infectiousness is probably proportional to that viral load. How much fluid escapes a person into the air also varies by a few orders of magnitude depending on whether they're sitting quietly enjoying a movie all the way to singing loudly.
- notabee 5y agoYou can if it's an average and you're not being overly literal about it. Don't break out a stopwatch and assume you're safe if you run out of the room before the average time is up.
- Symmetry 5y agoIt's not a matter of differences you need a stopwatch for, it's that the times plausibly vary between a second and years.
