- [Pre-print, not peer reviewed] Among 730,000 SARS-CoV-2 test results from Los Angeles from August to October 2020, a higher prevalence of SARS-CoV-2 asymptomatic infection was identified among individuals who reported work in construction compared to other occupations and who identified as members of racial and ethnic minority groups. The prevalence of asymptomatic infection among Hispanic individuals was 13.8% compared to 3.1% among non-Hispanic individuals. The authors also identified a higher prevalence of asymptomatic infection among individuals who had been contacted by a representative from a local health department regarding a known SARS-CoV-2 exposure.
