Coronavirus antibody testing finds Bay Area infections may be 85X higher

A team of researchers in California found that the number of coronaviruses cases in one county may actually be up to 85 times higher than the what health officials have tallied, and say their data may help better estimate the virus’ true fatality rate.

Earlier this month, Stanford University-led researchers tested 3,330 adults and children in Santa Clara County, who were recruited using Facebook ads, for SARS-CoV-2 antibodies and found that the population prevalence of COVID-19 in Santa Clara ranged from 2.49 percent to 4.16 percent.

Stanford Antibody Study is out -- LaneRat 04/18/2020 08:50AM

Apparently other common cold coronavirus are always around. ... -- DaveVT 04/18/2020 11:15AM

My understanding is these are specific to covid 19 -- Synaesthesia 04/18/2020 12:26PM

This makes sense. There is no way the virus propagated so quickly and far -- NWHokie 04/18/2020 10:25AM

The study itself suggests your guess is too high by order of magnitude ** -- Synaesthesia 04/18/2020 11:02AM

Maybe, but I still think 30% is realistic. ** -- NWHokie 04/18/2020 12:06PM

Yep. And results from randon c19 tests from town outside boston. 146/397 -- ColoVT82 04/18/2020 10:01AM

Serious Q for any of you experts... -- JoesterVT 04/18/2020 09:50AM

False positives are a very small %. Best way is to provide an uncertainty -- ColoVT82 04/18/2020 10:10AM

How do we know false positives are very low? ** -- JoesterVT 04/18/2020 10:15AM

I still think that study is way too small to mean much -- DaveVT 04/18/2020 09:26AM

Biggest problem with its dataset is likelihood of self-selection bias -- Synaesthesia 04/18/2020 11:11AM

Stanfords own conclusions say its enough to recalibrate predictions. Yes -- ColoVT82 04/18/2020 10:13AM

That’s what she said ** -- OXVT 04/18/2020 09:31AM

Do we have a good idea how long an asymptomatic person can spread the virus -- Tuckahokie 04/18/2020 09:05AM

If I had to take a SWAG... -- EDGEMAN 04/18/2020 09:13AM

Ive seen 24 to 28 days for the full cycle to fatality. Maybe 4? Days befor -- ColoVT82 04/18/2020 10:18AM
