Only 0.4% have contracted covid-19 in the U.S.
It means that 95% haven’t.
That’s confirmed cases, which mostly means people who have gotten sick.
These serology studies are trying to identify asymptomatic or mild cases that did not come to the attention of the public health system.
That’s how we get the .1% estimate of the IFR for the seasonal flue. It’s an important data point, and a matter of some urgency for the probably inevitable next waves of this CCP Virus.
It’s hard to say, but NYC and LA county are finding large local variations, but somewhere in a neighborhood of 15% up to 20%, and that was a couple of weeks ago.
Averaged over the country? No one has any idea, but my point in posting this is that’s irrelevant. This has to be understood locally, and the Spanish study which appears to be of high quality, is showing that clear as day.
Big in some regions, almost absent in others. Why?
It hits Men twice as hard as women. Why?
It is mild in almost every case for 5-7 days, then takes off like a wildfire. Why?
Some people had such mild symptoms, they didn’t even know they had it. Why?
It’s critical because we can’t just let the Blue state governors destroy the economy. We need to take this CCP Virus seriously, but we’ve got to get people back to work.
