Trying to remember the name of a play about a mysterious sexually transmitted disease set in post-apocalyptic Brooklyn

It’s about this couple and the guy is infected and essentially infected people are quarantined and guarded by cops because of how much of the city the disease has wiped out. The woman sneaks in to see her boyfriend and essentially begs him to have sex with her and is determined to die with him. Her name is Blue, can’t remember the male character’s name. It’s basically like an hour long argument between them and one of the final lines is “there’s death in this, Blue”. Anyone know what I’m talking about? It’s excellent and I’m trying to use it for an acting exercise and it’s driving me nuts not being able to find it. Thanks for any help!
