FAIRFIELD — Two local universities reported additional COVID-19 cases as the town continues to adjust to being added to the state’s list of municipalities at risk for potential virus spread.

Fairfield University reported an additional 11 COVID-19 cases among its community, while Sacred Heart University reported eight more cases.

The town was added to the state’s “red alert” zones Thursday after recording a rate of 19.6 virus cases per 100,000 residents from Oct. 4 through Oct. 17. Towns with 15 virus cases per 100,000 residents over a two-week period are considered “red alert” for coronavirus spread potential. Those areas have the option to revert back to Phase 2 restrictions of reopening.

There were 10 more cases in students and one in a staff/faculty member reported at Fairfield University on Thursday. The additional 11 cases put the university’s total number of active positive cases at 74.

In a statement Thursday night, Fairfield University officials said the school took immediate steps on Oct. 9 to implement “additional mitigation strategies within segments of our student populations.” Since following those strategies, officials said, the university saw a downward trend of positive cases. The university said it expects to see that trend continue.

“The university uses real-time data to determine daily the best course of action,” the statement said. “Fairfield’s active positive cases currently represent less than 1 percent of our total university population.”

The university said it saw limited numbers of virus cases during the first six weeks of the semester, which started to decline at the start of October.

Fairfield University saw an increase in case among “specific populations” of the student community toward the end of the first week of October, the statement said.

Sacred Heart reported eight additional cases on Thursday, four on-campus and four off-campus students, putting the school’s total number of active cases at 75.

The university said in a statement Thursday afternoon it would further limit on-campus activities and discourage unnecessary off-campus travel, even locally. All public events were canceled at the university for the foreseeable future.

But it wasn’t just colleges in Fairfield reporting new cases.

Quinnipiac University reported another 10 cases on Friday, since the university’s last update on Wednesday. All 10 were among off-campus students, several of whom were already quarantining after being previously in contact with confirmed positive cases.

At Yale University, officials reported another three cases — two among students and one among staff/faculty — as of Wednesday.

The University of New Haven reported 15 more cases among students, putting its total number of active cases at 54.
