Since HIV was discovered, approximately 86 million people have been infected.
If you are worried about a one in 86 MILLION chance of anything happening - anything at all - that is not an issue we can help you with.
There is nothing more to say about this no-risk event.
The only risks for HIV in adults are:
1) Having unprotected anal or vaginal sex, or
2) sharing intravenous needles with IV drug users.
Kissing, with or without blood, is not a risk for HIV.
