Table. Percentage of 5403 Cumulative SARS-CoV-2 Resident Cases Who Were Asymptomatic, Presymptomatic, or Symptomatic at Time of Initial Test in SNFs That Underwent at Least 1 Unit-Based or Facility-Wide Point Prevalence Survey as of July 15a.

Abbreviations: SARS-CoV-2, severe acute respiratory syndrome coronavirus 2; SNF, skilled nursing facility.
Counts represent the cumulative number of resident cases across SNFs in 2 testing categories: those who underwent 1 or more unit-based point prevalence surveys without ever undergoing facility-wide testing, and those who underwent 1 or more facility-wide point prevalence surveys. The cumulative case count includes cases detected during survey plus those detected during symptom- or exposure-driven testing at any time from March 16, 2020, to July 15, 2020. A case is a resident who was positive for SARS-CoV-2 on polymerase chain reaction testing. For residents who were tested multiple times, the first positive test date was used to determine symptom status. A resident was asymptomatic if they had no new symptoms from 5 days before testing to 14 days after testing; presymptomatic if they had no new symptoms in the 5 days prior to testing but developed symptoms up to 14 days after testing; and symptomatic if they had new symptoms in the 5 days prior to testing. The P value of an overall Pearson χ2 test is shown.
