Dr. Richard Bruno, site medical director at Chase Brexton Health Care in Mt. Vernon, wears a colorful cloth mask over his N95 respirator. To help stretch supplies, he has worn the respirator for up to a week even though it's meant for one-time use. His wife, Mary Bruno, is making cloth masks for him and members of his staff to boost morale. Bruno is in the door way of one of the COVIC-19 testing tents near the entrance to the building. This tent, one of several set up by IronMark, sits in front of an old teller's cage from the building's former owner, Monumental Life Insurance Company. (Kim Hairston/Baltimore Sun)
