Dr. Ebony Hilton, who is 38, is a professor and an anesthesiologist at the UVA School of Medicine. UVA’s hospital has some 600 beds, but at night Hilton often works alone: “I’m literally the only anesthesiologist attending for the entire hospital. At that moment, I can’t shut down, I can’t go to my room and let fear stop me.  … I don’t think any of us have slowed down to think that this could be the one that gets me sick. You don’t have time to consider options A, B, C and D. You’ve got to gown up and go.”
