  • After 2 members of the Hopi tribe tested positive for SARS-CoV-2, among 58 of their primary and secondary contacts (immediate and extended family and community members), 27 (47%) laboratory-confirmed SARS-CoV-2 infections occurred. Among all 29 infected individuals, 22 (76%) were symptomatic and seven were asymptomatic. The majority of people who had presymptomatic and asymptomatic infection were children and young adults. The authors suggest that among communities with similar levels of interaction with extended family, emphasizing ways to stay in touch that involve mask wearing, frequent hand washing, and physical distancing might help limit the spread of SARS-CoV-2.
