• [Pre-print, not peer-reviewed] A SARS-CoV-2 surveillance study in Orange County, CA conducted from July to August 2020 reported an adjusted SARS-CoV-2 seroprevalence estimate of 11.5%, which is 7-fold greater than the estimate using official County statistics on cases reported. To minimize bias, the authors recruited adults (n=2,979) to answer a survey without knowing they would be offered a SARS-CoV-2 serology test. Results also show that prevalence was elevated higher among Hispanic participants and among those participants with household income <$50,000.
