FORT COLLINS, Colo. (CBS4) – Colorado State University is taking extremely aggressive measures to try to halt the spread of COVID-19 on its Fort Collins campus. On Thursday night, CSU informed students in two residence halls — Braiden Hall and Summit Hall — that they must go into mandatory quarantine immediately. It came after wastewater testing for coronavirus determined that both dorms have levels that “are many times higher than others that we have detected on campus in past samples.”

“We are placing the entire residence hall into a mandatory quarantine. This means that you should not leave your residence hall for any reason, beginning immediately. The quarantine will be in place until all positive cases and close contacts in the residence halls have been identified and the wastewater results return to normal,” the university wrote to the residents of Braiden and Summit halls.
