You’ve probably heard about them in school… or while talking with your family or friends…they’ve definitely made appearances in movies. Yup, we’re talking about sexually transmitted infections or STIs for short. These infections are transmitted through all types of sexual activity. They can be common, but are preventable, so read and stay safe!


Teen Clinic chooses to use the term Sexually Transmitted Infection instead of Disease. The term disease can imply a clear medical problem with obvious signs or symptoms, however most sexually transmitted infections have no signs or symptoms, so we prefer the word infection.

  • Chlamydia
  • Gonorrhea
  • Pubic Lice (Crabs)
  • Syphilis
  • Trichomonaisis
  • HPV (including genital warts)
  • HIV
  • Herpes

For even more details on each infection, check of the Center for Disease Control. You can also ask us an anonymous question right on our website. If you are experiencing symptoms of an STI, think you’ve been exposed to an STI, or want to talk to a professional, call Teen Clinic to make an appointment with a qualified health care provider.
