SARS2 and infection: Our study of weekly SARS2 rtPCR surveillance of nasal specimens from adults and children over a period of one year spanning pre- and post-vaccine eras has several notable findings: (1) Weekly SARS2 surveillance by rtPCR identified no asymptomatic and only one pre-symptomatic SARS2 infections; (2) Social distancing from persons outside the household was associated with protection from SARS2 infection; (3) SARS2 vaccination was associated with fewer infections.
