The CDC documents COVID-19 Serology Surveillance strategy, types, and data at:
https://www.cdc.gov/coronavirus/2019-ncov/covid-data/serology.html
The current summary from CDC as of June25, 2020 is at this link:
https://www.cdc.gov/coronavirus/2019-ncov/cases-updates/commercial-lab-surveys.html
Note that all six surveys reported ended long before the peak infection period of this pandemic (last were Utah and Connecticut ended May 3).
The only current Serology Surveillance surveys not reported here are San Francisco and South Florida, neither of which would be of much relevance to the USA as a whole.
So I submit that they do NOT have any current data, and in fact are not even looking. That seems completely unacceptable to me!
Not looking, because they know that what they will find, will not support the political narrative they prefer?
Correction: The only current Serology Surveillance surveys not reported here are San Francisco, Minnesota, and Louisiana. No data for these 3 surveys (that I am aware of) has been published to date, and the relevance to the USA as a whole is not clear.
