ROCHESTER, N.Y. — St. John Fisher College is transitioning to online learning for the rest of the fall semester, as a result of a spike in COVID-19 cases within the campus community. 

The school says wastewater surveillance also shows an increased presence of the disease.

St. John Fisher says it has not reached the case limit set out by New York state, but the increased number of cases and the appearance of the virus in wastewater spurred the decision.

Undergraduate classes on Thursday and Friday are now canceled.

Students living on campus have been told to move home as soon as they can and to quarantine at home for two weeks. 

Classes will resume online on Monday.

The school says it is working on policies to refund or credit students for room and board charges.

The Monroe County Health commissioner says his department has worked with school officials during this process, and says he supports the decision to go fully virtual.

Monroe County Health Commissioner Dr. Michael Mendoza says his department has worked with school officials during this process, and says he supports the decision to go fully virtual.

"I commend the leadership, staff and students of St. John Fisher College for their diligent planning, preparation and actions over the past several months. They faced the unprecedented challenge of returning to campus during the COVID-19 pandemic and, undoubtedly, this cluster of cases could have been much worse without their efforts. The Monroe County Department of Public Health has worked collaboratively with college officials throughout the process and I fully support their decision to implement remote learning for the remainder of the semester. Let this serve as a reminder to our entire community that, until we have an effective vaccine, all of us must remain vigilant in working to contain the spread of COVID-19."
