Q and A


Why am I HIV negative if my boyfriend is HIV positive?

My partner and I recently went for an HIV test and my results came negative while his came positive. This is very strange because in the 2 years that we have been together, we hardly ever use a condom?

How does this come about? are there other cases like mine? is this possible?


Yes this is possible, and a lot of other people have been in the same situation.

You have just been very lucky.

The risk of catching HIV relates to many things, including your partners viral load (ie how infections he or she is).

In very early infection the risk could be a 1 in 10 per exposure or higher, but if it is very low or undetectable, this could drop to 1 in 3000 or less.

Depending on the type of sex you have, and how often, with these number you see how it could just be luck. You could still catch HIV the next time you are at risk. You should also have another HIV test in 3 months, to check that you were not infected in the few months prior to your original test.

A very small percentage of people (probably less than 2% in the UK), have genetic protection against HIV infection. There are no commercial tests that are able to check this.

While many people think (or hope) they have this protection, and that they will be lucky and not catch HIV if they don’t use a condom, in reality they are usually wrong. This is why numbers of new infections are still increasing each year.

Your partners diagnosis sounds like it was a shock for both of you. Take time to find good resources and support, both for your partner and yourself while you come to terms with what has happened. This affects people in all sorts of ways, but with good treatment and care, your partner can expect to lead a long life.

    Hello, The risk of catching HIV depends on many things. If you don’t use a condom then it can be just down to luck. But it will also depend on your partner’s viral load. If HIV is undetectable in his blood tests, then he’ll be less infectious than if he wasn’t on effective treatment.

    Using condoms will protect against HIV. But if a condom breaks then, yes you might get infected that way.

    Hello my partner is positive and I’m negative, and we didn’t use condoms sometimes. I’m scared but know I might be positive also. My question is what if a condom breaks and leaks his sperm, might I get infected that way?

  4. Hi Winnie,
    I’m sorry to hear about your boyfriend’s diagnosis. We have an FAQs page for couples in this situation. Have a look there and then let me know if you have any questions or would like any further information. It might help you both to get some support- the HIV clinic should be able to put you in touch with a local peer support group.

  8. Hi Owame. If you want to use condoms when you have sex your boyfriend should respect this- this is a decision that you should make together and you should not be pressured into having sex without condoms if you don’t want to. Having an undetectable viral load means that the risk of transmission is very low for vaginal sex- close to zero. But if you have any sexually transmitted infections this can increase the chance of passing HIV to your boyfriend. It is important that you are both treated for any infections before having sex without condoms. Having a miscarriage shouldn’t cause your viral load to increase.
