PORTLAND, Maine (AP) — Students at the University of Maine are returning to campus for the first time since being sent home in March.

Monday marked the start of move-in week in Orono just days after four students tested positive for the coronavirus.

At the University of Maine, two of the students are roommates and live off campus, and one student lives in a fraternity house. All three are showing mild symptoms and are quarantining. Also, a returning, out-of-state University of Maine Law student was quarantining after testing positive, officials said Monday.

“Our screening strategy is working as intended, identifying and isolating a case of COVID-19 that might otherwise have gone undetected and possibly spread infection on our campus and in our classrooms,” said UMaine President Joan Ferrini-Mundy.

The university system is testing all students who are returning from out of state and all students who are living in campus residence halls.

BROADBAND ACCESS

Maine's Republican senator has cosponsored legislation to authorize $2 billion to support distance learning and telehealth amid the pandemic.

Sen. Susan Collins is working with Democratic Sen. Joe Manchin of West Virginia and Republican Sen. John Cornyn of Texas on the proposal. Collins said better access to broadband is critical for rural and low-income residents to be able to access education and healthcare.

The proposal is about “helping to close the digital divide for rural and low-income residents in Maine and throughout the country,” Collins said.
