If you have an STI, or had one recently, contact all the people you’ve had sex with recently and suggest they get tested. Sometimes this isn’t easy. You might find it hard to tell your sex partners you have an STI.

It is important to talk to your sex partners so they can get tested and treated too. Remember, if one partner is untreated, many STIs can be passed back and forth.

Sometimes a sexual health centre will anonymously contact sexual partners for you.
