Opinions please???

Jessica

Never seen ringworm in person. His cheek started with a rash a few days ago and this is whats left now. He also had a middle of the night vomit the night before last. Do we think this is a ringworm or just part of the rash left over from a virus or something else?? Please, I'm super paranoid about ringworm for some reason! The skin on his face is pretty dry.
