![]() This investigation adds to the body of evidence demonstrating that children of all ages are susceptible to SARS-CoV-2 infection ( 1– 3) and, contrary to early reports ( 5, 6), might play an important role in transmission ( 7, 8). Asymptomatic infection was common and potentially contributed to undetected transmission, as has been previously reported ( 1– 4). These findings demonstrate that SARS-CoV-2 spread efficiently in a youth-centric overnight setting, resulting in high attack rates among persons in all age groups, despite efforts by camp officials to implement most recommended strategies to prevent transmission. †† Finally, it was not possible to assess individual adherence to COVID-19 prevention measures at camp A, including physical distancing between, and within, cabin cohorts and use of cloth masks, which were not required for campers. Second, given the increasing incidence of COVID-19 in Georgia in June and July, some cases might have resulted from transmission occurring before or after camp attendance. First, attack rates presented are likely an underestimate because cases might have been missed among persons not tested or whose test results were not reported. The findings in this report are subject to at least three limitations. Among 136 cases with available symptom data, 36 (26%) patients reported no symptoms among 100 (74%) who reported symptoms, those most commonly reported were subjective or documented fever (65%), headache (61%), and sore throat (46%). During June 21–27, occupancy of the 31 cabins averaged 15 persons per cabin (range = 1–26) median cabin attack rate was 50% (range = 22%–70%) among 28 cabins that had one or more cases. Attack rates increased with increasing length of time spent at the camp, with staff members having the highest attack rate (56%). The overall attack rate was 44% (260 of 597), 51% among those aged 6–10 years, 44% among those aged 11–17 years, and 33% among those aged 18–21 years ( Table). Test results were available for 344 (58%) attendees among these, 260 (76%) were positive. The median age of staff members and trainees was 17 years (range = 14–59 years), and 59% (148 of 251) were female. Median camper age was 12 years (range = 6–19 years), and 53% (182 of 346) were female. Attack rates were calculated by dividing the number of persons with positive test results by the total number of Georgia attendees, including those who did not have testing results, because negative test results are not consistently reported in Georgia.Ī total of 597 Georgia residents attended camp A. Out-of-state attendees (27) were excluded from this preliminary analysis. ![]() A COVID-19 case associated with the camp A outbreak was defined as a positive viral SARS-CoV-2 test** in a camp A attendee from a specimen collected or reported to DPH from the first day at camp A (June 17 for staff members and trainees June 21 for campers) through 14 days after leaving camp A (trainees left on June 21 staff members and campers left during June 24–June 27). DPH recommended that all attendees be tested and self-quarantine, and isolate if they had a positive test result.Ī line list of all attendees was obtained and matched to laboratory results from the State Electronic Notifiable Disease Surveillance System ¶ and data from DPH case investigations. On June 25, the Georgia Department of Public Health (DPH) was notified and initiated an investigation. Camp A officials began sending campers home on June 24 and closed the camp on June 27. The staff member was tested and reported a positive test result for SARS-CoV-2 the following day (June 24). On June 23, a teenage staff member left camp A after developing chills the previous evening. Camp attendees were cohorted by cabin and engaged in a variety of indoor and outdoor activities, including daily vigorous singing and cheering. Cloth masks were required for staff members. Measures not implemented were cloth masks for campers and opening windows and doors for increased ventilation in buildings. Camp A adopted most † components of CDC’s Suggestions for Youth and Summer Camps § to minimize the risk for SARS-CoV-2 introduction and transmission. Camp A adhered to the measures in Georgia’s Executive Order* that allowed overnight camps to operate beginning on May 31, including requiring all trainees, staff members, and campers to provide documentation of a negative viral SARS-CoV-2 test ≤12 days before arriving. During June 17–20, an overnight camp in Georgia (camp A) held orientation for 138 trainees and 120 staff members staff members remained for the first camp session, scheduled during June 21–27, and were joined by 363 campers and three senior staff members on June 21. Limited data are available about transmission of SARS-CoV-2, the virus that causes coronavirus disease 2019 (COVID-19), among youths.
