[Pre-print, not peer-reviewed] A prospective surveillance study of SARS-CoV-2 infection and antibody prevalence among farmworkers in California’s Salinas Valley from June 15 to November 30, 2020 found 22% positivity for nucleic acid detection among workers tested at federally-qualified migrant and community health clinics, as compared to 17% among other adults from the same communities (RR=1.3). In a nested study enrolling 1,115 farmworkers, prevalence of current infection was 28% among participants reporting ≥1 potential COVID-19 symptom, and 7% among those without symptoms (aOR=4.2). Prevalence of anti-SARS-CoV-2 IgG antibodies increased from 11% during July 16 – August 31 to 21% during November 1 – 30.
