Results from a SARS-CoV-2 antibody seroprevalence survey (July 10 to August 16, 2020, n=2979) from a socioeconomically and demographically diverse population of adults in Orange County, California found a seroprevalence of approximately 12 percent. Antibody testing was conducted using a highly specific and sensitive CoVAM microarray. This SARS-CoV-2 point seroprevalence among adults for July to August 2020 is seven-fold greater than the cumulative incidence of diagnosed cases reported to Orange County.
