Asymptomatic and Presymptomatic Severe Acute Respiratory Syndrome Coronavirus 2 Infection Rates in a Multistate Sample of Skilled Nursing Facilities

Educational Objective
To identify the key insights or developments described in this article
1 Credit CME

Asymptomatic transmission of severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) may be a major contributing factor in skilled nursing facility (SNF) outbreaks. However, limited knowledge exists regarding the prevalence of asymptomatic and presymptomatic infection in this setting. Although an estimated 40% to 45% of SARS-CoV-2 infections in the general population are asymptomatic at time of testing,1 a small number of US and international reports have documented higher asymptomatic rates in SNFs.25 We examined asymptomatic and presymptomatic infection rates in a large multistate sample of US SNFs, and examined variation in case counts by SARS-CoV-2 prevalence in the counties where SNFs are located.
