Districts where major colleges and universities opened to teach classes in the fall experienced a significant increase in the incidence of Covid-19, according to a new study from the U.S. Centers for Disease Control and Prevention.
Within three weeks of the opening of colleges or universities, the places where these institutions were located "suffered a 56% increase in incidence," the CDC-led research team wrote in the agency's weekly report.
Meanwhile, the researchers found that the incidence decreased by 5.9% in counties without universities and by 17.9% in those with universities teaching online.
Researchers, from the CDC and the U.S. Department of Health and Human Services, examined fall class schedules posted on the websites of major colleges and universities in the United States.
They saw which institutions conducted online classes and which conducted physical education in early September.
They also analyzed Covid-19 incidence estimates in areas where online instruction was provided, where classroom instruction was provided, and where there were no universities.
The researchers noted that places where learning took place normally were more likely to be identified as "hotspots".
The study did not consider mitigation strategies, such as wearing masks and social distancing. More studies needed, porn in general, the CDC posted on its official Twitter page this week that students, faculty and staff should wear a mask, stay 6 feet away and avoid rallies "to slow down the spread" .
