Can I get HIV by only one time unprotected anal sex with HIV positive partner


Dear Sir or Madam

I'm 29 and homosexual and circumcised. Last 13th May 2016 I had experienced unprotected sex with male partner. I had two times intercourse with this partner and the first time (at night) I used condom and gel correctly but in second time (at early morning) I had intercourse again and I used lubricant and condom at initial stage, then I removed condom at middle stage and I think after just 5 minutes I made ejaculation. One month later after happening it, I've known that my partner is HIV positive. So, I went to clinic and tested HIV with ELISA Test at 6 weeks (41 days) exactly. Fortunately, my result was negative but I can't happy till now and I'm worrying about HIV. Can I transmit HIV by only one time anal sex and my testing with HIV result after 6 weeks can reliable. What can I do for my so much and continuous concern? Please give me your opinion upon my event.
Thank you so much for your help.


Hi there, and thanks a lot for contacting the AIDS Vancouver Helpline for you HIV/AIDS related health information.

It sounds like you are concerned about your risk of HIV transmission as well as the reliability of your HIV test results..

Unprotected Anal sex, regardless of how many times it is performed, is considered a High Risk activity. This means that it presents a potential for HIV transmission because it can involve an exchange of body fluids. In addition, a significant number of scientific studies have repeatedly associated the activities with HIV infection. There have been a lot of confirmed reports of infection in this way.

The ELISA test is the most commonly available HIV test. It is a blood test that looks for antibodies. The Elisa test is 99.8% accurate.

Most infections are delectable within 4-6 weeks post exposure. You had your test at 6 weeks when 95% of infections are delectable and it came back negative. This is good.

I understand that you are still very concerned about your test results. All HIV tests are considered conclusive at 3 months post exposure. For your own peace of mind, I would encourage you to have another test done at 3 months when your test results are considered conclusive.

I would encourage you to check out the following resources about HIV:
