Why partner notification matters
If you have been diagnosed with an STI, any recent sexual partners may have been exposed. Partner notification — the process of informing those partners so they can test and treat — is a critical part of breaking chains of transmission. Untreated STIs can cause serious long-term health complications and can be passed on unknowingly. Most people, when approached respectfully and given accurate information, appreciate being told.
How far back should you notify partners?
The recommended look-back period depends on the infection. For chlamydia and gonorrhea, the standard guidance is to notify partners from the past 6 months, or all partners since the last negative test if you have one. For syphilis, the period extends further — up to 3 months for primary syphilis, 6 months for secondary syphilis, and 1–2 years for early latent syphilis. Your health department STD clinic or clinician will give specific guidance for your diagnosis.
How to have the conversation
There is no single right way, but clarity, brevity, and empathy work best. Choose a private moment — not by text unless face-to-face genuinely is not possible. Stick to the facts: what you were diagnosed with, that they may have been exposed, and that they should get tested. You do not owe an explanation of your entire sexual history. Most partners will be more understanding than you anticipate. Rehearsing the conversation in advance, or speaking to a counselor at a clinic, can help with anxiety.
Can the clinic notify partners on your behalf?
Yes. Many health department STD clinics and public health departments offer confidential partner notification (partner services). A trained health adviser can contact your partners anonymously — without revealing who asked them to get tested. This is called "provider referral" and is a helpful option if you find direct disclosure difficult, if you do not have contact details for a partner, or if you are concerned about a negative reaction.
