get new roommates

I moved into a 1000 square foot apartment with my best friend and his gf. We have a small living room. My roommates decided to go to a four day frat party for NYE and came down with covid. Someone at the house came down with symptoms on the last day yet they didn’t feel the need to tell me for two days. But somehow when I respectfully asked them to follow guidelines and not to sit on the couch WITH COVID, I immediately was screamed and cursed at and called “fucking ridiculous”. But yeah... I’m the asshole.
