There's no way anyone can tell you what happened. The best thing for you to do is to get tested for hepatitis and other blood-borne diseases.
transmission only happens with blood to blood contact. just get checked if you really want to know
transmission like blood to blood like say i had a cut on my lip (not recent) or they were chapped, or like i recently got a cut
Bart, get tested for the whole lot.....
I think you worry too much about catching diseases, reading from all your other posts. I think that the most important for you is to try to work on eliminating that constant fear.
Good luck, Marcia
