The camp adopted some mitigation steps found in CDC Suggestions for Youth and Summer Camps to minimize the risk for SARS-CoV-2 introduction and transmission to include cohorting of attendees by cabin and enhanced cleaning and disinfection. However, the camp did not require the 363 campers to wear masks, only the staff. Additionally, camp attendees engaged in a variety of indoor and outdoor activities that included daily vigorous singing and cheering, which might have contributed to transmission.
