Hey @Native, the coronavirus evolution video you posted in the locked thread showed a figure in which the R0 in the US is way higher than in Italy or Spain (and higher than in most other countries). That surprised me, and is pretty damned scary. It would be nice to know whether that is based on older data, prior to isolation measures in the US, or whether that represents the current state of affairs.
I'd have to go back and listen again. Maybe will tomorrow. R0 going to have a variety of assumptions at this point. So he likely has a more updated, recent source, or someone who used a different set of assumptions. Like most of this, until antibody tests show who was exposed, no one has a clue, given the asymptotic nature of the infection in a large percentage of individuals.
