According to the latest report from the Centers for Disease Control and Prevention, in the summer, a coronavirus outbreak raged during the overnight stay in a school in Wisconsin. It was first a student and then eventually infected more than 90% of teenagers and counselors.
The six-week faith-based training camp requires testing and isolation of all participants from 23 states and territories and two foreign countries one week before the retreat from July 2 to August 11. Soon after arriving, a ninth-grader at the camp tested negative for the virus at home and developed symptoms including sore throat, cough and chills. The CDC reported that a PCR test was then performed on the student and the result was positive.
Except for the 24 participants who had passed the antibody test to provide evidence that they had been infected with the virus and recovered from it, 91
Although all high school-age boys must wear masks when they go to the camp, they can wear masks when they arrive at their destination and communicate freely. Students and 21 counselors sleep nearby: students live in 4 to 6 rooms in each room in the dormitory, 8 rooms in each room in the yurt, and the counselor lives in each room in the dormitory and yurt Together.
After the ninth grade student tested positive, he was isolated from his 11 close contacts. After 11 contact tests were negative through the rapid antigen test, they were released from the quarantine area. However, in the first week of the camp, 6 out of 11 people and 18 others reported new episodes of mild symptoms. The researchers wrote that these students were put on masks, but they were not isolated or contact tracing.
The Wisconsin Department of Health received notification of the epidemic on July 15 and checked 148 of the 152 retreat participants on July 28. Antibody tests showed that 91% (116 out of 128) of those who were not infected before arriving at the camp were infected there.
None of the teachers who lived apart from the student and the counselor who always wore a mask during class and kept social distance at all times tested positive for the disease.
All diseases are mild, and no deaths or hospitalizations have been found.
Dr. Stuart Ray, professor of infectious disease medicine at the Johns Hopkins School of Medicine in Baltimore, said: “In terms of the number of infections and the speed of infection, the attack rate is very high.” He said: “This illustrates the difficulty of control. “
Dr. Waleed Javaid, director of infection prevention and control for the Mount Sinai City District in New York, believes that the outbreak is not surprising given that students and counselors can mix freely and do not need to wear masks or social distancing. Said.
Javaid said: “This shows that a negative test does not mean that we should not distance ourselves from society.” “At some point, especially in the early stages of infection, the test may be negative and does not automatically indicate that a person is not infected. We need to wear masks and maintain social distancing at public gatherings.”
