• Description:
  Most U.S. overnight youth camps did not operate during the summer of 2020 because of the COVID-19 pandemic* (1). Several that did operate demonstrated that multiple Prevention strategies, including pre- and postarrival tTesting for SARS-CoV-2, the Virus that causes COVID-19, masking, and physical distancing helped prevent the introduction and spread of COVID-19; in contrast, camps that relaxed Prevention strategies, such as requiring a single prearrival test without subsequent tTesting, experienced outbreaks (2-4). The availability of COVID-19 vaccines for persons aged ≥12 years enabled implementation of an additional Prevention strategy that was not available in summer 2020. This study assessed the number of COVID-19 cases and potential secondary spread among 7,173 staff members and campers from 50 states, 13 countries, and U.S. military overseas bases at nine independently operated U.S. summer youth camps affiliated with the same organization. The camps implemented multiple Prevention strategies including vaccination, tTesting, podding (cohorting), masking, physical distancing, and hand hygiene during June-August 2021. Vaccination coverage was 93% among eligible persons aged ≥12 years.| All staff members (1,955) and campers (5,218) received site-specific, protocol-defined screening tTesting, which included prearrival tTesting and screening tests during the camp session (38,059 tests). Screening tTesting identified six confirmed COVID-19 cases (one in a staff member and five in campers) by reverse transcription-polymerase chain reaction (RT-PCR) tTesting (screening test positivity rate = 0.02%). Three additional cases (in two staff members and one camper) were identified based on symptoms and were confirmed by RT-PCR tTesting. Testing for SARS-CoV-2, isolation, and quarantine in a population with high vaccination coverage resulted in no known secondary Transmission of SARS-CoV-2 identified during camp. Implementation of multicomponent strategies is critical for Prevention of COVID-19 outbreaks in congregate settings, including overnight youth camps.
