So question. I& #39;m obviously no epidemiologist, but re studies purporting to show that there& #39;s already a high % of asymptomatic seropositive people: if true, how do you explain catastrophic outbreaks in places like NYC where we know there has been large-scale spread?

Also, with the flu comparisons, I recall someone pointing out that we& #39;ve never bothered to find out the "true" IFR for the flu -- there are probably asymptomatic cases of that too.
