The attack rate was highest among staff members (56%).
However, the CDC statement noted that the camp "did not require the 363 campers to wear masks, only the staff".
Hundreds of children contracted the coronavirus at a summer camp in the USA state of Georgia last month, health authorities said Friday, adding to a growing body of evidence that minors are both susceptible to infection and vectors of transmission. Campers were a median age of 12, and 53% were girls, while staff members were a median age of 17, and 59% were girls. "Camp attendees were cohorted by cabin and engaged in a variety of indoor and outdoor activities, including daily vigorous singing and cheering". PEOPLE has partnered with GoFundMe to raise money for the COVID-19 Relief Fund, a GoFundMe.org fundraiser to support everything from frontline responders to families in need, as well as organizations helping communities.
The staff member was tested for SARS-CoV-2 - the novel coronavirus - on June 24 and got a positive result the same day. The first known case involved a teen camp staff member who developed chills on June 23 and tested positive for COVID-19 the next day. The entire camp was closed June 27. On June 25th, local health officials and the CDC began investigating the outbreak, advising that every camp attendee get tested and self-isolate for two weeks if positive.
Among 597 Georgia residents, including campers, staff members, and trainees, the attack rate was 44%, reported Christine M. Szablewski, DVM, of the Georgia Department of Public Health, and colleagues.
51 of the campers are in between the age of 6 to 10 and 180 are in between 11 to 17 years of ages, according to the report.
Among 136 cases with symptom information available, 26% reported no symptoms, with the authors specifically characterizing asymptomatic transmission as "common". Of those who reported symptoms, the most commonly reported were subjective or documented fever, headache, and sore throat. Of these, more than three-quarters (260 people) tested positive, with high rates of infection across every age group.
While the results are imperfect - for instance, it's possible some of the cases traced the camp were actually due to transmission in the day before after attendance - they're startling in light of the national debate about school reopenings.
The authors added that the findings contribute to a body of evidence "demonstrating that children of all ages are susceptible to SARS-CoV-2 infection and, contrary to early reports, might play an important role in transmission".
The findings also underscore the importance of mitigation measures if and when schools reopen.
"Physical distancing and consistent and correct use of cloth masks should be emphasized as important strategies for mitigating transmission in congregate settings".
