“He tested positive.”

“He” is an elderly African-American man, prone on an I.C.U. bed behind the sliding glass doors. There is the usual ugly pink rubber tube in his mouth, attached to the breathing machine. He has the intravenous contraption, and monitor electrodes on his chest. His heart is beating fast. Nurse Mulligan is injecting saline into his IV. At least I think it’s Nurse Mulligan. I can’t quite tell, because she’s encased in yellow with a yellow paper hat, a blue N95 mask, and a second mask with a visor.
