How can I know if I have a sexually transmitted infection (STI)?

Talk to your healthcare provider. He or she can examine you and perform tests to determine if you have a sexually transmitted disease. If you think that you have an STI, it's important to see your healthcare provider. Treatment can:

  • Cure many STIs
  • Lessen the symptoms of STIs
  • Make it less likely you will spread the disease
  • Help you to get healthy and stay healthy
  • Provide you with information on how you can prevent getting and spreading STIs
