Orange County reports 229 new COVID-19 cases, 1 death

County officials hired UCI to do a serological study of a large cross- section of residents to check antibodies for COVID-19 to get a better handle on how prevalent the highly infectious disease has been in the community, according to Kim. The study showed that “the disease prevalence is about seven times greater than previously identified by positive tests,” Kim said. It also showed that coronavirus infections were “greater in Latino and lower-income residents, which we knew because they had a higher positivity rate.”
