Telling a partner you have chlamydia is one of the most uncomfortable conversations you can have, but it’s also one of the most straightforward. Chlamydia is the most commonly reported bacterial STI, it’s curable with a short course of antibiotics, and your partner needs to know so they can get treated too. The hardest part is starting the conversation. Once you do, most people find it goes better than they expected.
What to Say: Specific Phrasing That Works
The best approach is direct, calm, and factual. You don’t need to over-explain or apologize excessively. A simple, honest statement gives your partner the information they need without drama. Here are a few ways to frame it depending on your situation:
For a current partner: “My results came back positive for chlamydia. It’s totally treatable and the doctor prescribed medication for me. You probably have questions, so ask away.” This works because it immediately reassures them that treatment exists, and it invites them into the conversation rather than making it a monologue.
For a casual or former partner: “I was just diagnosed with chlamydia and my clinician recommended that my previous partners get tested. It doesn’t always cause symptoms, so even if you don’t have any, you should still get tested to be safe.” This version is more informational and less emotionally loaded, which fits the dynamic of a less serious relationship.
For a long-term partner where trust feels fragile: “I went in for routine screening and found out I have chlamydia. The doctor thinks it’s important that my previous partners get tested to protect their health.” This framing centers the medical reality rather than blame. Chlamydia can remain dormant without symptoms for months or even years, so a positive test doesn’t automatically mean recent infidelity.
Pick the Right Moment
Have the conversation in a private, low-stress setting. Not in bed, not during an argument, not at a party. Choose a time when you’re both relatively calm and won’t be interrupted. If you live together, a quiet evening at home works well. If you don’t, suggest meeting up somewhere you can talk privately.
In-person conversations are ideal for current partners because they allow for tone, eye contact, and real-time reassurance. A phone call is a reasonable second choice. For former or casual partners, a text message or phone call is perfectly acceptable, and many people actually prefer receiving this kind of news in a format that gives them time to process before responding.
If You Can’t Tell Them Directly
Some situations make face-to-face disclosure difficult or unsafe. Maybe you’ve lost contact with a past partner, or the relationship ended badly, or you’re worried about how they’ll react. Anonymous notification services exist for exactly this reason.
TellYourPartner.org, a CDC-referenced service, lets you send an anonymous text to a sexual partner alerting them that they may be at risk for an STI. The message never reveals your identity. Research shows that anonymous notification options increase the rate of partners actually getting tested and treated, which is the whole point.
Your local health department can also help. Many offer partner notification services where a public health worker contacts your partner(s) on your behalf without disclosing your name. You can ask your doctor or clinic about this option when you receive your diagnosis.
Who Needs to Know
The standard recommendation is to notify anyone you’ve had sexual contact with in the 60 days before your symptoms started. If you didn’t have symptoms (which is common, since chlamydia is often silent), the 60-day window starts from the date your test sample was collected. If your most recent sexual contact was more than 60 days ago, that person should still be notified.
This isn’t just about being considerate. Untreated chlamydia has real consequences. About 10 to 15 percent of women with untreated chlamydia develop pelvic inflammatory disease, which can lead to chronic pain, ectopic pregnancy, or infertility. In men, untreated infections can cause pain and swelling in the reproductive tract. Notifying your partners gives them the chance to avoid these outcomes with a simple course of antibiotics.
What Your Partner Should Do Next
Your partner should get tested, but timing matters. Chlamydia testing is most accurate when done at least one week after exposure, and waiting two weeks catches nearly all infections. If your partner gets tested too early, they could get a false negative.
There’s also a shortcut available in most of the country. Expedited partner therapy allows your doctor to prescribe antibiotics for your partner without your partner needing a separate medical exam. This is legal in 48 states and Washington, D.C. You can pick up the prescription and bring it to your partner directly. It’s especially useful when a partner doesn’t have easy access to a clinic, lacks insurance, or is unlikely to schedule their own appointment. Ask your prescribing doctor about this option.
When You Can Have Sex Again
You need to wait at least 7 days after completing your antibiotic treatment before having sex again. If you were given a single-dose medication, the 7-day clock starts from the day you took it. If you were prescribed a week-long course, wait until you’ve finished all the pills and any symptoms have cleared. This applies to all sexual contact, not just intercourse.
Both you and your partner need to complete treatment before resuming sexual activity together. If only one of you is treated, you’ll pass the infection right back. This back-and-forth reinfection is one of the most common reasons people test positive for chlamydia more than once.
Handling Their Reaction
Your partner might be upset, confused, scared, or surprisingly calm. All of these are normal. Some people’s first reaction is to wonder about cheating. Be prepared for that question and answer it honestly, but also know that chlamydia can be asymptomatic for a long time. It’s genuinely possible for someone to carry the infection from a previous relationship without knowing.
Stick to the facts: chlamydia is extremely common, it’s curable, and you’re telling them because you care about their health. If they need time to process, give it to them. If they have questions you can’t answer, suggest they call their doctor or a sexual health clinic.
Some partners will thank you. Telling someone about an STI is an act of respect, even when it doesn’t feel like it in the moment. Most people, once the initial surprise fades, recognize that you did the responsible thing.
