It's not a stupid question. Some "research" last week said it could hang around for several minutes and I posted...Right. Stupid question alert.
I vape right. And when I exhale the cloud if you like can travel much further than 2 metres if it catches a breeze. Also even if it’s not windy it can hover for someone else who was 2 metres away initially to walk through (I’m conscientious about this don’t worry).
Appreciate particles are different sizes and fall to the fall quicker and that jazz but are we saying covid19 particles can’t get caught on a breeze and travel much further? I know it’s been said it’s not really an airborne disease but if an infected jogger for example passes me at the 3 or 4 metres on a windy day is that really sufficient?
Which is why it would be really useful to know how much likely infection is if you pass a jogger rather than if you pass where he was seven minutes ago.
Still no answer! I've not found the bluemoon epidemiologists forum yet though.
