Q and A

Question

A condom burst with my positive girlfriend. Will I have HIV now?

I had sex with my girlfriend and the condom burst while i was inside her. She sent me an SMS a week later and told me she is HIV positive. I didn’t ejaculate inside her. I want to know if there is any chance i did not get infected?

Answer

Hi

Thanks for your question – and the quick answer is that you are much more likely to still be negative. Catching HIV from one broken condom is a very low risk.

The risk of transmission is also lower if your girlfriend is on treatment. She should also have had something called a viral load test. Someones viral load tells you how much virus is in their bloodstreat. The lower this is the lower the risk of transmission is.

If your partner is not on treatment the risk of transmission is about 1 in 500.

If she is on treatment and has an undetectable viral load the risk becomes zero. This is because when viral load is this low, transmission doesn’t occur.

All of this means that you are more likely to be negative than positive.

Taking a test is still a good idea as a routine part of your own sexual health check up.

You can find more information about HIV transmission here.

The answer to Q9 at this link have more information about the need for condoms when viral load is undetectable.

    Hi Janet

    This service doesn’t answer questions about testing and transmission, because the information is already online at the FAQ page.

    HIV is quite a difficult virus to catch, but if this happened in the last day or so please read the information on PEP.

    Hi Shaun, HiV is a difficult virus to catch. The very rough estimates from a single risk for vaginal sex without a condom are about 1 in 300, perhaps lower. If your partner is HIV negative then the risk is zero. The text only means your partner was HIV negative about 4-8 weeks before the test. The meds taken after a possible exposure are called Post Exposure Prophylaxis (PEP).

    PEP is usually only given where there is a definite high risk, but this is partly your decision about it you want to take 30 days of combination therapy for a small risk. This balance is your decision. The earlier PEP is started the more likely it will work – ie hours is better than days and not after 48-72 hours.

    I had sex last night and the condom burst. What pills can I take to prevent HIV? However, the lady tested 2 weeks agao and she was negative but I am scared though.

    Unfortunately, we no longer answer questions about transmission and testing. This information service is about HIV treatment for people who are HIV positive.
