2 doesn't seem all that likely going by this (preprint) study. It seems to be a bit more infectious than SARS and MERS but a secondary attack rate of only 14-20% in household would be about the same as other ARIs.Antibody study suggests coronavirus may be far more widespread than previously thought
Non-peer reviewed study from Stanford found virus may be 50 to 85 times more common than official figures indicatewww.theguardian.com
1000 confirmed case but estimated 48000-80000 people with antibody. I am guessing....
1. The virus circulated much earlier.
2. The virus is more infectious.
3. There are much more asymptomatic people than previously estimated.
4. USA testing sucks.
5. The study is flawed.
1 seems very likely to me, especially in California but there's no proof. 3 and 4 are almost a given.
5 probably a bit because a ~0.1% IFR would be on the very low end.
Yesterday's report. Today's isn't out yet, I think.Quite the increase in Germany again. Almost 4k.... I've read the RKI has started publishing the "infection rate" (R0) somewhere, but I can't find it.
