The university campus is COVID “Superspreader”

Wednesday, January 13, 2021 (HealthDay News)-Researchers warn that US universities could be COVID-19 superspreader sites, and the first two weeks of class are the most dangerous.

They surveyed 30 campuses nationwide with the highest number of coronavirus cases and found that in the first two weeks of the class, more than half had spikes of well over 1,000 cases per 100,000 people per week. discovered.

On some campuses, one in five students had been infected with the virus by the end of the fall semester. There were more than 5,000 cases in four schools.

On 17 campuses, computer modeling showed that college outbreaks were also directly associated with infection peaks in the county where the school was located.

Fortunately, researchers also found that tight control of outbreaks (such as immediate switching from face-to-face learning to online learning) could reduce the peak of infection within about two weeks.

This study was published in the journal on January 13th. Computer techniques in biomechanics and biomedical engineering..

Compared to the peak incidence of 70 to 150 per 100,000 people per week in the first and second waves of the COVID-19 pandemic, the proportion of 1,000 cases per 100,000 people per week found in this study is very high for universities. Shows high risk Hannah Lu, lead author of the Stanford University Energy Resources Engineering Program, said the infection rate was high.

“Policymakers often use the incidence of 50 COVID-19 cases per 100,000 people per week as a threshold for high-risk counties, states, or countries. Of the 30 in our study. All institutions exceeded this value, and three were also double digits of that size. “Lou said in a journal news release.

“The number of students infected throughout the fall has more than doubled the national average since the outbreak of 5.3% began, with a population of 328.2 million and reported 17.3 million,” she said.

For example, all 12,607 students at the University of Notre Dame were tested before the start of the class, and only nine were positive. Within the two weeks of his term, the 7-day incidence was 3,083.
