Standard swab and saliva sample collection during the study period. COVID-19 = coronavirus disease 2019. * Inclusion criteria were age ≥18 y, provision of informed consent, and being high-risk asymptomatic or having mild symptoms of COVID-19. Patients were screened before entry by a physician. Those with severe symptoms were redirected to an emergency department for formal clinical evaluation. † Eight participants were tested twice at the testing center (for both standard swab and saliva sample). Two tested positive on their initial oropharyngeal swab and negative on a saliva sample. These participants' results remained positive on an oropharyngeal swab and negative on a saliva sample on repeated testing (5 d and 8 d later). One participant tested positive on the initial oropharyngeal swab and negative on the saliva sample. This participant tested negative on both specimens 7 d later. The remaining 6 participants tested negative on initial and repeated testing for both specimens.
