This summer, after a student developed symptoms and infected 91% (116%) of students and counselors, a coronavirus outbreak raged during a summer middle school retreat in Wisconsin this summer.
This alarming outbreak was discussed in a new study by the Centers for Disease Control and Prevention released on Thursday.
The “Super Spread” event took place at a faith-based educational retreat for high school students in grades 9-11 from July 2 to August 11.
The retreat included 152 boys, counselors and from 21 states and regions and two foreign countries. Everyone was required to be tested and quarantined the week before the camp.
But a ninth grade student tested negative at home and began to show symptoms shortly after he arrived.
The teenager underwent a PCR test and the result was positive. Soon, with the fall of preventive measures, the virus will spread during the retreat.
According to the Centers for Disease Control and Prevention, the Wisconsin Department of Health Services received an alert regarding the outbreak on July 25.
Three days later, department officials tested 1

The Centers for Disease Control and Prevention reported that a faith-based overnight event broke out in Wisconsin this summer. They tested 148 students, faculty and staff, and found that 91% of them contracted the virus when they retreated.The count excluded 24 students who had previously been infected and recovered

Although all retreat participants must wear masks when they travel to Wisconsin camps, they are allowed to play with mask suggestions and communicate freely with each other.
Some students slept four to six in the dormitory room, while other students slept eight in the yurt room. Twenty-one counselors live in similar dormitories or yurts.
After the ninth grade student received a positive diagnosis, he and his 11 close contacts were quarantined in the camp. According to the rapid antigen test, all 11 contacts tested negative and have been released from the quarantine area.
However, during the first week of training camp, 6 of these 11 boys-plus 18 other boys-were experiencing mild symptoms.
Masks were worn to these students, but they were not isolated from others and continued to spread the virus unknowingly.
The retreat administrator did not track contacts, so the possibility of an outbreak is greater.
Teachers who do not have a positive diagnosis are present, they engage in social distancing, wear masks and live apart from their students and counselors.
There were no reports of deaths or hospitalizations from the outbreak.
Now, the CDC has reiterated the importance of disaster reduction work after the school-age outbreak.
The official wrote, “SARS-CoV-2 can spread rapidly in a crowd environment, and COVID-19 mitigation measures are insufficient.”
“A strong COVID-19 mitigation plan developed in cooperation with public health authorities is essential to prevent and contain similar outbreaks in overnight camps and boarding schools.”

The CDC study pointed out that the silver lining in the outbreak is the potential link between antibodies and the coronavirus.
An important feature of this outbreak is that 24 participants had recorded evidence of anti-SARS-CoV-2 antibodies before arriving. None of these people received a positive result of SARS-CoV-2 RT-PCR test at the retreat.
These findings provide preliminary evidence that detectable antibodies may provide protection against new SARS-CoV-2 infections for an unknown duration.
The agency still warned that more investigations into the link must be conducted. At this time, “the evidence so far is insufficient.”
Wisconsin ranks 11th in the number of recorded coronavirus cases, with 227,000 infections and more than 2,000 deaths.
Since the first outbreak in January, the United States has reported more than 8.9 million infections and 228,600 deaths.
