Welcome to the Forum. I see that you have asked the same question of Teak on the HIV Prevention Community site. I agree with what he has said. the exposure you describe is virtually no risk and not a reason for concern. Concerns are cuts and scrapes are not justified as such wounds do not get the secretions, even if they were infected (which is very unlikely) deep into wounds. Superficial contamination just is not a meaningful cause of HIV transmission.
In answer to your specific questions:
1. No, se my comment above.
2. Low. Most sex workers do not have HIV, particularly if they do not use IV drugs. The prevalence of infection in CSWs varies from place to place but on average, the likelihood that she was infected is less than 1 in 100.
3. Correct. The quoted figure for HIV risk, if one has oral sex with an infected partner is less than 1 in 10,000 and, in my estimation that is too high. Some experts state there is no risk at all from oral sex. Neither of us on this site have ever seen or reading the medical literature of a convincing instance in which HIV was passed by oral sex.
4. I would anticipate that the cut allowed introduction of the HPV, increasing your likelihood of infection. It might have happened without the cut but clearly scrapes increase the risk of infection.
5. Anything could happen in theory but the likelihood is close to zero. This is not something to worry about.
6. There really is no medical reason for testing related to this exposure however if it will give you peace of mind, then you should go on and get tested. After 6 weeks (now) a test would detect over 95% of infections acquired 6 weeks earlier and at 8 weeks well over 99% of infections will be detectable, Either way, whether you get tested now or later, I predict the result will be negative and when it is, I URGE you to accept this as verification that you did not get infected.
Forget about ARS, you have a cold. This is later than ARS would occur and ARS is very, very rare while colds are very common. Take care. EWH
While having gential HSV has been associated with increased risk of getting HIV if exposed, with yoru current test resutls and the details you ahve provided, it remains almost certain that you did not get HIV from the expsoure you described. EWH
Thankyou for your response that is most helpful and confirms/puts to rest most of my anxieties. However I did forget to mention that I also have HSV-2, and while I did not have an outbreak at the time, I did get an outbreak a week after the incident, probably due to worrying and guilt. Does this change anything with respect to your answers above?
