I feel like you have more to say than you are saying.
If there was no blood, there was no HIV. If the wound had a scab, there was no way for HIV to get into the bloodstream.
For HIV to occur, one needs three things. One, a fluid HIGH in HIV. (Blood, semen, vaginal fluids and breast milk). If any of these fluids are not present, HIV will not occur.
You then need an activity. Unprotected sex, sharing dirty needles, childbirth and breast feeding.
The last thing you need for HIV to occur is a way to the bloodstream.
You might be worried about the saliva but saliva does not have enough HIV to cause infection.
What are you worried about?
Always
