Category: Article Summary

Topic: Clinical Characteristics and Health Care Setting

• [pre-print, not peer-reviewed] A study among workers at a multi-site healthcare system in LA County estimated SARS-CoV-2 antibody seroprevalence post–stratified on demographic group (n=15,000 invited; 6,062 participated). Overall seroprevalence was 4.1% (95% CI 3.1, 5.7%), with lower estimates in older workers (aOR = 0.8, 95% CI 0.7, 0.9) and higher estimates in Hispanic workers (5.7%; 95% CI 3.9, 8.3%; aOR = 1.8, 95% CI 1.3, 2.4). Significantly higher estimates were also observed for African American race (aOR=1.8, 95% CI 1.1, 2.9), and for workers with asthma (aOR=0.5, 95% CI 0.3, 0.8).
