Symptoms of STIs


Most people with an STI have no symptoms.


Some STIs will cause very obvious symptoms, but many STIs cause no symptoms or only mild symptoms - so you might not know you have an infection.


If you do have symptoms, they may appear right away, or they might not show up for weeks or even months. They might come and go. Even if the symptoms disappear, you may still have an STI. A test from your healthcare provider may be the only way to tell if you are infected.


Get tested if:


  • You've had  sex with a new partner without using a condom (external or internal/female condom or dental dams).
  • If you or your sexual partner have had sex with someone else without using a condom. 
  • If the person you have sex with has any symptoms.

Possible symptoms of STIs:
