Is your roommate ill, or are you just speculating that ne might have one of the conditions that you fear? Did you ask him if he used your toothbrush? And why do you keep a few HBV test kits around?
You seem to have a lot of anxiety. Maybe consider speaking to a professional about that.
First off your room mate would have to be infected in order for you to catch anything. Since this is the HCV forum I will address that. The only way to transmit HCV is for infected blood to get into an open, bleeding wound on you. There is a chance with the toothbrush, but it is very slight.
Life has enough stress without worrying about unnecessary things. Get both yourself and your room mate tested and quit worrying about it
What other tests do you have lying around? Don't you have gloves since you have such a tremendous fear of HBV? Alcohol swabs? Something protective?
Why would your roomate use your toothbrush anyway doesnt he have his own?
Why don't you go to your family doctor and explain all this to him. He not only can give you advice regarding exposure but can also recommend a professional who will counsel you regarding your obsession with contracting infectious diseases.
I don't get the using another person's toothbrush. My 13 year old niece over the summer bounced out of the bathroom saying that she used my toothbrush but rinsed it well. Shortly after that I was diagnosed with acute hcv. Geez - ya just can't do that - it's weird -only my opinion- but it is weird.
Actually... long before I knew I had HCV... if I discovered that somebody used my toothbrush, my first reaction was to boil the thing before I used it again
