The Asymptomatic #COVID19 Infection Rate.
@danieloran, my colleague @ScrippsRTI, compiled all of the available data, links, text and details from 8 cohorts: https://www.scripps.edu/science-and-medicine/translational-institute/about/news/sarc-cov-2-infection/index.html
We">https://www.scripps.edu/science-a... believe the rate is ~40% (from top 3); the others w/ higher rates are difficult to interpret.

Yes, some patients in these series were actually pre-symptomatic, but those data were not reported. The advantage of the Vo, Italy study was a sequential assessment which ruled that out; the asymptomatic rate was 43%
