My friend's husband has become very, very worried about certain things, namely that he will pass diseases onto their daughter, etc. They are diseases that he doesn't have. Namely, he as of late stopped brushing his teeth
because his gums bleed when he does? And he is worried he will pass hepatitis onto their daughter. He does not have hepatitis, but someone in their building does. 
He doesn't seem to need rituals or anything else I'd associate with OCD, though when he comes in he needs to scrub up in the bathroom for a long time. It's just germs mainly.
Does this sound like OCD, or something else? It's certainly not normal behavior, is it?! My friend and I have only talked about it briefly but when we speak next I'm going to encourage her to help him talk to someone. She's a professional therapist by the way.
again! He's done things in the past which are certainly odd but it all seems to be getting out of hand now.
