Abstract

Our analysis of coronavirus disease prevalence in 9 long-term care facilities demonstrated a high proportion (40.7%) of asymptomatic infections among residents and staff members. Infection control measures in congregate settings should include mass testing-based strategies in concert with symptom screening for greater effectiveness in preventing the spread of severe acute respiratory syndrome coronavirus 2.

Keywords: 2019 novel coronavirus disease; COVID-19; California; SARS-CoV-2; United States; assisted living facility; coronavirus disease; long-term care facilities; severe acute respiratory syndrome coronavirus 2; skilled nursing facility; zoonoses.
