That information will be coming in
This study from Santa Clara County did antibody testing on a random set of people on April 3 and April 4... Results were only published today, April 17, which shows how long it takes to get everything right.
In order to show that everything we think we know, may be wrong again (although this may not be a great study, they recruited their subjects via Facebook ads!)
Quote:
the population prevalence of COVID-19 in Santa Clara ranged from 2.49% (95CI 1.80-3.17%) to 4.16% (2.58-5.70%). These prevalence estimates represent a range between 48,000 and 81,000 people infected in Santa Clara County by early April, 50-85-fold more than the number of confirmed cases.
Conclusions
The population prevalence of SARS-CoV-2 antibodies in Santa Clara County implies that the infection is much more widespread than indicated by the number of confirmed cases. Population prevalence estimates can now be used to calibrate epidemic and mortality projections.
