Attention IPAC practitioners: an R of 2.5 is not evidence that sars-2 is not airborne. Rather, an R that is usually < 1, but can be 60 or 100 (i.e., overdispersion) is STRONG evidence that when this infects, it infects via aerosol.

Never understood why more attention was not devoted to this. If we could target events that lead to clusters, it becomes a really rubbish

I don't either, really. It's an obvious chokepoint and weakness. I think a lot of Western public health had a sticky prior with flu because we were expecting an influenza pandemic.

How frequently has one individual given rise to multiple outbreaks spread apart by 1/2/3/etc. days. Just had the crazy thought that if people's most contagious 1 hr could be more contagious than by an order order of magnitude that would give rise to overdispersion.
