(PCR for influenza, respiratory syncytial virus and SARS-CoV-2)
One hundred thirty-one tests for SARS-CoV-2 were obtained and 7 were positive ( 5.3% ; 95% CI, 2.2%-10.7%). The median age of patients who tested positive was 38 years (range, 34-44 years), 3 were male (43%), and the median duration of symptoms was 4 days (range, 2-4 days) at presentation. Six of 7 patients presented with fever, 5 with myalgias, and only 1 with cough. Only 1 patient had a travel history (returned from Miami, Florida). All patients had mild illnesses, and all tested negative for influenza and respiratory syncytial virus.
