For Teens: Get Checked for STIs

Look for symptoms

Not all STIs have symptoms you can see. For example, chlamydia usually has no or only mild symptoms. But knowing common signs, such as irritation and pain, will help. Pay attention to your body and your partner’s body. If either of you see or feel something that seems like a symptom, get checked.

Get checked

Getting checked is the only way to know for sure if you have an STI. You can get tested at a health clinic or healthcare provider’s office. Tests may include:

• Physical exam

• A sample (swab) of the penis, vagina, mouth, or rectum

• Urine tests

• Blood tests

• HIV testing by blood test, finger stick, or oral swab

• A sample of tissue, cell, or saliva

• A pelvic (vaginal) exam or rectal exam

Get treated

Many STIs can be cured or treated with medicine. Early treatment can help keep things from getting worse. Follow all your instructions for treatment. And remember to:

• Not have sex for as long as you’re told. If the infection is not completely gone, you could infect someone else. 

• Take all your medicines. And don’t share medicines with your partner unless you’re told to.

• Go back to your healthcare provider or clinic if your symptoms don’t go away (or if they come back).

• Get treated for each STI you have.

Talk to your partner

If you have an STI, tell your partner so they can get checked. It may be embarrassing. But if you don’t talk about it, your partner could end up having serious health problems. They could also pass the disease back to you or on to others. If you’re not sure what to say, ask your healthcare provider or nurse.

Treatments to prevent an HIV infection are also available. Talk with your healthcare provider about prevention options if you are sexually active or have been diagnosed with an STI in the past.
