That's not correct, at least in hospitals and apartment buildings there was pretty good evidence that SARS was airborne, at least over short distances. Yes, I mean actually airborne, not ballistic droplets. I'm not thinking "yeah sure I knew that" in hindsight like people quite often do, this is from research I did in 2018. I wore P100 elastomeric respirators from the start of the pandemic, I didn't question for a second that it was airborne.
