“I think you and I are in complete agreement.”
I think we are really close! There were ‘aerosol deniers’ on on these threads in the past, but they’ve pretty much been silenced by the facts. They thought a bit of bleach and Purrell would keep them safe - sorry, not happening, not that easy, not even close.
Anyway, I think the only difference is that I’m implying from what you’re saying (maybe incorrectly) is that viruses actually ‘live’ in ventilation systems and reproduce there, as in Legionnaire’s Disease, whereas I’m saying that while closed ventilation systems circulate viruses, they can’t actually increase the number of virons or the concentration of them...those systems let them build up, but to increase the total number, you need infected people, dumping more virons into the closed environment - and they have to be dumping more faster than the virons are dying off.
We are in complete agreement!
I didn’t mean to imply that the virus is multiplying on its own in ventilation.
Just that in closed systems a small viral load will infect a new person and that person will add to the viral load in the ventilation. So another person, or another few persons will get infected from the ventilation, and will add to the virons in the the vents. Then more people will get infected breathing the same air in the closed system, etc. etc.
Because this virus is airborne!
