- aRelative risk of asymptomatic/symptomatic probabilities of infection
- bRelative risk of symptomatic/asymptomatic probabilities of infection
- cThe number of total samples evaluated for prevalence and risk analysis is lower than the total study population by removing invalid PCR results (N = 3187) and exclusion of sequential Positive Results within 90 days of each other (N = 1346), for a total of 4533 excluded from this analysis
