STI without symptoms: still get tested and notify your partner
Most people with chlamydia have no symptoms. The same is true for gonorrhea, mycoplasma, and sometimes even early-stage syphilis. No symptoms does not mean: no risk to a partner.
No symptoms ≠ no STI. Testing and notifying can still be the caring choice.
Why can you have an STI without noticing it?
Many sexually transmitted infections are asymptomatic: the immune system does not produce a visible response, or symptoms are so mild they are easily overlooked. The infection can still be transmitted to partners in the meantime.
STIs that often occur without symptoms
Chlamydia
An estimated 70–80% of women and 50% of men with chlamydia have no or minimal symptoms. Untreated, it can still lead to complications and is easily passed on.
Gonorrhea
In women, gonorrhea is most often asymptomatic. In men symptoms are more common, but not always present.
Mycoplasma genitalium
Almost always asymptomatic, but long-term infection can cause damage and is transmitted through sexual contact.
Syphilis (early stage)
The initial sore (chancre) disappears on its own after a few weeks. Anyone who misses it may not know there is an active infection.
Herpes (HSV-2)
Many people with genital herpes never have a recognizable outbreak, but can still transmit the virus through asymptomatic viral shedding.
When to test if you have no symptoms?
Consider testing if: there was a new or multiple sexual contact; you had unprotected sex; a (ex-)partner informed you of possible exposure; you have not been tested in a while but are sexually active. Your local sexual health clinic offers free testing for risk groups. A GP or certified clinic can also test. Home tests are available for those who prefer discrete testing.

How do you notify a partner when you had no symptoms?
It can feel awkward: you felt fine, yet you need to let someone know. A neutral, brief message is usually best. You do not need to explain when or how. The act is what matters: giving the other person the chance to get tested.
- Keep it factual and short: "I learned I may have been exposed. I'd recommend you consider getting tested."
- Point to testing options without pressure: mention a local clinic, GP, or suitable option.
- If direct contact feels too confrontational, an anonymous message via PrivaNotify can help.
- Send the message once. Repeated unwanted contact stops being care and becomes pressure.
What not to do
- Wait for symptoms before telling someone — with asymptomatic STIs, they may never come.
- Share unnecessary detail about your diagnosis if you do not want to.
- Make accusations — you often cannot know for certain where an infection came from.
- Put panic or shame in the message — it blocks the recipient from taking action.
