Contagious Itchy Rash, Fungal? Help

So I got bit by quite a few mosquitos about a week ago, and they have morphed into a couple monstrosity dry, flaky, beyond itchy spots. They’re also spreading like crazy, my roommates now both have them as well and they’re mad at me and blaming me. I don’t know what to do. One of them got tested at urgent care and they said it wasn’t ringworm. It feels like it might be but I just don’t know what to do. Also I’m lowkey a hypochondriac so this is a terrible idea asking about what it might be, but I just need help. If I’m gonna die or if it’s something really scary, please let me down easy.
