Sorry to hear of your mishap in efforts to do a good deed. The cut on your hand will have no consequences for you in terms of HIV or hepatitis. You are correct that oral secretions represent a hostile environment for secretions and the open air is even harder on them. Thus, even if he had HIV or hepatitis (unlikely) and even if he was REALLY sloppy, had the virus been there is would not be viable and you would not be at risk. You do not need to worry. You do not need testing to evaluate your risk from the exposure you describe. Hope this helps. EWH
Thanks a lot for your response!
G-d bless you!
