I have never had a patient who acquired HIV from a specific heterosexual exposure to a sex worker. It is rare for anyone to catch HIV after PEP, but my personal experience doesn't help; I haven't personally prescribed PEP to anyone for several years.
Hello Dr Hunter. I was able to take PEP treatments till the end. Now waiting for test. I still very nervous and paranoid on it. Can I count with your pacience to answer these questions:?
Have you seen in your experience cases of infection by this single and very brief exposure (15 seconds insertive anal)
Have you seen in your experience cases of people taking PEP timely and for the role 28 days and still geting positive results? Is it common?
Thanks once more.
PEP is believed to be highly effective when started as soon as you did. Between the low risk of the exposure and the effectiveness of PEP, your chances of being infected indeed are very close to zero.
Good luck with it.
Dr hunter thanks for your promptly responses and advices and the patience dealing with paranoid frightened people like me. I've dicided for the PEP and started 30h after exposition. 150mg lamivudine+300mg zidovudine. Last question to close this topic. can I assume chances came close to zero considering the aformentioned episode combined to PEP treatment? Many thanks
It probably is unlikely your partner had HIV; in general, heterosexually transmitted HIV is rare in Spain. But follow the advice of a local doctor or clinic about whether or not to take PEP. If you do it, you'll go through up to 6 months of uncertainty about your status. If PEP isn't effective, in theory it might delay positive test results, so testing can be fairly prolonged. Without PEP, definitive testing can be done after only 4-6 weeks. So if the local experts believe it is unlikely your partner is infected, think very carefully before you decide to go ahead with PEP.
She is female! I met her in a bar at Spain! I don't know her status! I think that I'll seek for pep! Do you think that following pep instructions ill still have enough chances to be worried with? Thanks!
Welcome back to the forum.
We can disregard the oral sex. Even if your partner had HIV, there is virtually no chance of transmission from an oral to penile partner.
With anal sex, of course the risk is higher -- one estimate is that if the anal partner has HIV, the penile partner has one chance in about 500 of being infected. Perhaps the risk would be lower with the brief exposure you describe, but that really isn't known; it might not make much difference.
As for PEP, you don't provide enough information. If you know your partner had HIV, or if he was a male, PEP may be wise. And maybe also if your partner is female and at high risk for HIV (e.g., injection drug user, commercial sex worker, African American, or with other high risk markers). If so, you should promptly seek care from a doctor or clinic with experience in HIV and its prevention, or at a hospital emergency department or urgent care clinic, and follow their advice about PEP. However, PEP probably isn't necessary if your partner is not at particularly high risk.
I hope this has helped. Best wishes-- HHH, MD
