Twenty Boston College students have tested positive for coronavirus — the vast majority of whom had returned from traveling abroad, according to the college’s president, William P. Leahy.

In an update shared with the college community on Monday, Leahy wrote that 19 of the students who tested positive “returned directly to their homes or to off-campus apartments” from their travels abroad. One student diagnosed with COVID-19 was on campus, and is now in isolation at an apartment complex that houses students from the college.

Leahy noted that staff members have been cleaning and disinfecting campus buildings and common spaces multiple times a day.

“No doubt, this pandemic has particularly affected the Class of 2020, and I am saddened by that,” Leahy wrote. “Senior year is a special time in the life of a college student, and I know our seniors were eagerly awaiting such events as Marathon Monday, Senior Week, and Commencement.”

Leahy said he would update the community on plans to hold commencement, which is presently scheduled for May 18.

" If that should not be possible, every effort will be made to have a suitable event to honor graduating students at a later date," he said.
