People are saying that 90%-95% of SARS-CoV-2 transmission is via the air, and only 5%-10% via touching things. All the advice about washing your hands was wrong; handwashing or lack thereof is almost completely irrelevant, though still good wash on general principles.https://twitter.com/JonHaidt/status/1261622978195992578 …
We have reasons to suspect its not actually 0%. This is a pretty good natural experiment. Of course it's possible he got it from airborne droplet transmission also. https://www.youtube.com/watch?v=lYC6oQIAzbI …

yeah I'm like 99% sure that if he did get the disease, it was from the air in that crowded indoor space full of people & not from touching stuff.

If he's the only one who caught it from whoever spread it into that room it's suggestive; not definitive either way though.
