What is the risk of HIV after a homosexual encounter?

This Premium Q&A, reviewed and published, features a real conversation between an iCliniq user and a physician.

Patient's Query

Hello doctor,

I am a 22-year-old male. Yesterday I had sex with a guy. We had protected anal sex for one to two minutes only. Apart from this, we both had oral sex. At first, we had unprotected oral sex and after that we had protected one. None of us ejaculated during the whole sex. After one day I am having sores in the penis and mouth. Now I am having a fear of getting HIV.

So, I want to ask that what are the chances in the above situation of getting AIDS if my partner is HIV positive? When should I get tested for HIV if supposed I had sex today? Can I have a PCR-HIV test for now and how accurate is this?

Hi,

Welcome to icliniq.com.

I need the following details to help you better. Whether your partner is infected with HIV or has a history of multiple sexual contacts?

The chances of transmission of HIV are higher among homosexual individuals. Have you noticed these ulcers frequently, or how long these ulcers have been present on your genitals?

I hope this helps you.

Thank you.

Patient's Query

Thank you doctor,

I had sex with a homosexual. The day after our sex I found some sores on my penis. I got sores on the penis once in three to four months. Can I still have chances of HIV? Can I go for a PCR-DNA test? And will HIV happen to every HIV negative person when they had unprotected sex with a positive person?

Hi,

Welcome back to icliniq.com.

The window period for the PCR DNA test is two to three weeks of exposure. So this test can be taken between two to three weeks (14-21 days) after your sexual encounter.

A confirmatory test may be taken only if your PCR DNA test result is positive. If it comes back negative, you may retest at the third-month mark for conclusive results. International guidelines state that an HIV test is considered definitive and conclusive when taken three months after exposure.

If you are now past the window period for the PCR DNA test, you may opt to get an antibody test done, e.g., third-generation ELISA or rapid test. As long as condoms are used accurately (i.e, using the right size, no breakages, using only one condom at a time), then they are a great way to prevent the transmission of HIV. As you said that you had recurrent genital ulcers, there were a number of causes, possibly even STDs.

I hope this helps you.

Thank you.
