N2 - In this prospective cohort study, 30 health care personnel with a known SARS-CoV-2 exposure provided oropharyngeal swabs for polymerase chain reaction (PCR) testing and blood specimens for serologic testing at 2 time points postexposure. At a median 7 days postexposure (range, 1-13 days), none had a positive PCR and 1 (3%) had a reactive antibody test. No additional participants were PCR or antibody-positive at a median 25 days postexposure (range, 14-36 days).
