To keep the virus off a campus, test beyond its borders, a new study suggests.

A new analysis suggests that schools and colleges, large companies, and other organizations that wish to protect themselves with consistent collective testing must think beyond their personnel.

By dedicating a large portion of their trials to people from the surrounding community, they can reduce the number of Kovid-19 cases among their members by up to 25 percent, researchers Report in a new paper, Which has not yet been published in a scientific journal.

Harvard University’s computational biologist and Broad Institute head of analysis Drs. Pardis Sabeti said, “Its outbreak is natural for people to become self-serving, self-centered. But he said,” If you’ve been in enough outbreaks, you just understand that in a box of tests Makes no sense. These things are communicable, and they are coming from the community. “

The study “has a really profound effect, Especially if others can repeat it, David O’Connor said that a virologist at the University of Wisconsin, Madison, who was not involved in the analysis, but reviewed a draft of the paper.

At the onset of the epidemic, when testing resources were in short supply, many colleges proposed intensive, expensive testing regimes that focused solely on their main campuses. When he did the dr. Asked for Sabiti’s advice, he said, he told her that he should test friends, relatives and neighbors of his students and staff.

It was not an easy idea to sell without data on its effectiveness, so Drs. Sabetty and his colleagues developed an epidemiological model of how a virus could spread through a midsize institution, the University of Colorado Mesa, and what would happen under various health policies. They found that allocating some tests to community contacts would significantly reduce the expected number of Kovid cases on campus.

Now according to Amy Bronson, co-chairman and author of the university’s Kovid-19 task force, CMU offers free trials to all of its students’ self-reported contacts, and runs a test site open to local residents. Paper.

And in November, University of California, Davis, Started visiting Free Coronavirus tests for anyone living or working in that city.

“A virus does not respect geographic boundaries,” said Brad Pollock, an epidemiologist at UC Davis who directs the project. “It is imperative to think that you can get control of acute infectious respiratory disease in a city like Davis like Kovid-19, which coordinates a very large university, without coordinated public health measures that connect both the university and the community. . “
