Welcome to the Forum. Your worries are misplaced. With or without a torn cuticle, this as a no risk event for all of the reasons that you are already aware of. The theoretical risk of you getting HIV from this exposure is about the same as your theoretical risk of being struck by lightning while reading my reply, i.e. there is no realistic reason for concern.
As for your specific questions:
1 I’ve read that vaginal secretions have a smaller concentration of HIV than semen or blood has. Is it true?
The concentration of HIV in vaginal secretions is highly variable and depends on many things. Typically it is lower than the level in blood but sometimes such as when another STI is present, HIV levels can actually be higher than in blood. This does NOT change the no risk nature of your exposure.
2 How fast the wounds small like this heal? Is it true that a small superficial wound which happened 1-2 hours ago don’t leave anything inside the bloodstream? I would like to notice that when I put my wound to a lemon 2 days after the incident it still hurt so it may had tissues which are TARGET HIV CELLS? Or should it go the bloodstream?
Wounds close off to surface contamination within minutes of exposure. Again NO RISK. That it could be irritated by lemon juice is irrelevant.
3 Mr. Handsfield analysis as how the virus spreads and he wrote that it has to be massaged into the tissues. Can’t it happen with an incident like this?
No.
4 In day 13, shouldnt I feel ARS symptoms if I infected? I read that at least one of the three main symptoms (high fever, sore throat, rashes) presents in day 10-14.I don’t have any of these.
Typically all of the symptoms of the ARS occur at about the same time and that is between 2 and 6 weeks after an exposure.
5 How’s it this different than a vaginal intercourse when the penis has small injuries?
The skin of the finger is very different from the skin of the penis, among other facts.
6 What is my risk?
Zero
7 Do I need testing?
No, testing is a waste of time.
I hope my comments are helpful to you. For you to worry about this is a waste of your time. follow-up questions will not deal with hypothetical, "what if" questions. EWH
Theoretical questions are "what if" questions and most of this question is repetitive and already answered above. There is NO RISK. Each of the factors you mention contribute to the abbsence of risk. Risk would not be higher with a larger wound. EWH
Thank you very much Doctor Hook, your answers were really helpful and convincing. I promise that there will be no what-if questions, I understand that there is no risk here.
As for theoretical risks, is the fact that the wound was not fresh (13-14 hours old) and just 1-2 mm big made the theoretical risk negligible as well? I mean if it was 10-20 minutes old, the theoritecal risk would have been bigger, right?
Thank you very much one more time and have a wonderful weekend!
One additional question:
I also heard that HIV need glycoprotein to spread and cuticles contain a lot of glycopretein. Could it be dangerous? Thank you and besz regards!
