After testing 344 attendees of YMCA Camp High Harbour at Lake Burton, in Clayton, Georgia, the CDC found that 76 percent tested positive for the coronavirus, and of those, 51 percent were between the ages of 6 10.
The report noted that it had three limitations: firstly, cases may have been missed among people who were not tested; secondly, some cases may have resulted from transmission before or after attending the camp, due to increasing incidence of the CCP virus in Georgia in June and July; and thirdly, it is uncertain how many at the camp were compliant with COVID-19 prevention measures.
On the second night of camp, a staffer came down with the chills and left the next day. They tested positive for Covid-19, and the camp began sending kids home on June 24.
It adds, "Among 136 cases with available symptom data, 36 (26 percent) patients reported no symptoms; among 100 (74 percent) who reported symptoms, those most commonly reported were subjective or documented fever (65 percent), headache (61 percent), and sore throat (46 percent)".
Masks were required for staff members. The summer camp outbreak added to Georgia's already dismal numbers with more than 170,000 confirmed positive cases and over 3,600 deaths. The staff member was tested and reported a positive test result for SARS-CoV-2 the following day.
These were included in the agency's recently released guidance to reopen USA schools.
The camp, which was not named, took a number of precautionary steps to prevent an outbreak, including requiring staff members wear cloth masks.
The attack rate is the total number of new cases divided by the total at-risk population. Health officials said "relatively large" groups of kids slept in the same cabin where they regularly sang and cheered, likely leading to spread.
The CDC mentioned that on June 17, employee got here for a four-day orientation for at an overnight summer camp unknown by the report.
While sleepover camps are not schools, and staff members are not teachers, the authors said the camps adopted CDC guidelines for youth and summer programs.
The CDC concluded their study by reminding everyone that "physical distancing and consistent and correct use of cloth masks should be emphasized as important strategies for mitigating transmission".
In a recent study of an outbreak at a high school in Jerusalem that began 10 days after in-person classes resumed in late May, 13% of the student body and 16% of the staff ultimately tested positive.
Almost 600 people were at the overnight camp, which was not named in the report by Georgia health officials and the Centers for Disease Control and Prevention.
While the role children play in the spread of the virus has been questioned, the authors of the report said the research adds to evidence that children of all ages are not only susceptible to infection but may play an important role in transmission. Among the 31 cabins, the COVID-19 infection rate averaged 50%.
Asymptomatic infection was common and potentially contributed to undetected transmission, the CDC said.
