The prevalence of having SARS-CoV-2 real-time RT-PCR positive test results in this population was moderate (8.7% overall; 4.7% for asymptomatic participants); administering the test in a lower prevalence setting will likely result in a lower PPV. Among 11 participants with antigen-negative, real-time RT-PCRpositive specimens with positive viral culture, five were symptomatic and six asymptomatic. Some antigen-negative, real-time RT-PCRpositive specimens possibly could represent noninfectious viral particles, but some might also represent infectious virus not detected by the antigen test.
