  • Chamie et al. tested 3,953 people who live or work within a census block in San Francisco and found a point prevalence of SARS-CoV-2 infection (by PCR) of 2% and an estimated cumulative incidence (by antibody testing) of 6%. Among those with positive PCR tests, 95% were Latinx and 53% were asymptomatic when tested. Among those with positive antibody tests, 67% were Latinx. The census district has a population of 5,174 people, of whom 58% are Latinx, 34% are white/Caucasian, 5% are Asian/Pacific Islander, and 1% are Black/African American.
  • Risk factors for recent infection were Latinx ethnicity, inability to shelter-in-place and maintain income, frontline service work, unemployment, and household income under $50,000 per year. [EDITORIAL NOTE: A related pre-print for this article was included in the Lit Rep on June 17th, 2020.]
