SARS-CoV-2 Seroprevalence among a Southern U.S. Population Indicates Limited Asymptomatic Spread under Physical Distancing Measures
Category: Article Summary
Topic: Geographic Spread
Keywords (Tags): geographic spread
- The seroprevalence of anti-SARS-CoV-2 IgG among people accessing health care for reasons other than COVID-19 symptoms in a low-density, suburban and rural population in North Carolina was 0.8% (24 of 2973) of outpatients and 0.7% (10 of 1449) of inpatients. Participants were sampled between March and June 2020, when state restrictions and physical distancing mandates were in place. Serological testing was performed with the Abbott SARS-CoV-2 IgG assay. The authors state that the low prevalence suggests that shelter-in-place mandates and physical distancing practices may have limited asymptomatic spread.
