[Pre-print, not peer-reviewed] Mask adherence among children in US summer camps was approximately 34% according to a survey of 486 summer camps that operated in 2020. Approximately 15% of camps reported one or more confirmed COVID-19 cases in either campers or staff, with three camps reporting a COVID-19 outbreak. Among the types of non-pharmaceutical interventions implemented, facial coverings among campers were associated with the lowest risk of COVID-19. Facial coverings among staff and targeted physical distancing measures reduced COVID-19 risks, but not as effectively as campers wearing masks. Pre-camp quarantine was not associated with reduced risk of COVID-19.
