Our findings establish the feasibility of an on‐site influenza test‐and‐treat strategy in shelters that has the potential to be applied during influenza epidemics and pandemics. Our genomic data suggest that intra‐shelter spread of influenza viruses is common and is responsible for a large proportion of symptomatic influenza virus infections in shelters. Possible distinct transmission dynamics within family and adult shelters suggests that interventions tailored to shelters serving children should be explored (e.g., on‐site antiviral treatment for symptomatic residents and chemoprophylaxis for exposed residents, baloxavir‐only treatment for children ≥ 5 years old,
