UCI study suggests as much as 11.5% of O.C. residents may have already had coronavirus

“There was this lurking suspicion that there’s a large fraction of people that have it that did not know,” UCI Public Health Associate Professor Tim Bruckner said in a UCI news report Wednesday. “Either they had no symptoms and did not seek care, or they did not have symptoms and had no reason to go.” An even higher rate of Orange County Latinos and low-income residents who participated in the UCI study — 17% and 15%, respectively — were found with antibodies indicating they had already been infected with the coronavirus.
