Getting around while sick at BU

BU's campus stretches along the Charles River, so a trip to the nearest clinic can mean a long walk or a T ride.

You may be riding the Green Line B branch along Commonwealth Avenue. Wear a mask on the T while you wait for your test result, and do not share drinks or utensils.

Living situation at BU

Many BU students live in off-campus apartments in Allston, Brighton and Fenway, where roommates share kitchens and bathrooms. Do not share cups, towels or utensils with roommates until you have taken antibiotics for 12 to 24 hours.
