Question

Can we have unprotected sex if we have the same strain of HIV?

Hi,
I was infected by my (long-term) partner few months ago (we both have good CD4 results and without treatment). We are together for many years and for many years have been practicing unsafe sex together.

As a lot of recommendations say that two HIV-positive people should use condoms to prevent superinfection by a stronger type of virus. I completely understand it in situations when I would like to have an unprotected sex with other unknown positive person. But in our case, when we have both the same subtype of virus, is there a real risk of superinfection and a negative impact on our state if we practice unsafe sex?

It’s a strange feeling after years start using condom between us (or course, with other people we use it every time from when we were diagnosed).

Thank you very much.

Answer

Hello,

Thank you for your question.

If you are infected with the same strain and neither of you has any resistance to HIV treatments then there should be no problem with you continuing to have sex without using condoms.

The main risk from superinfection/reinfection is if one person has resistance to some HIV treatments or a different type of HIV. This sound like it is not the case for you and your partner.  You can check your level of resistance to HIV treatment with a simple test. A resistance test is routinely recommend for all newly diagnosed people in the UK. Please talk to your HIV doctor about this.

    Hello, I had sex with a lady who is living with HIV and not on medication. Can it be passed on? We have sex one week.
