clammyChlamydia is a common sexually transmitted bacterial infection of the vagina, penis, anus or throat. Chlamydia is the number one most reported STI among youth in the United States.


Chlamydia is spread through vaginal fluids and semen. People get Chlamydia through vaginal, anal, or oral sex without a condom or dental dam.

Symptoms & Complications

Most people don’t have any symptoms.  For people who do get symptoms, it can include:

  • painful urination
  • painful ejaculation
  • pelvic pain
  • change in discharge (this could mean change in color, odor, consistency, or amount)

Like all bacteria, Chlamydia will multiply when left untreated. If an infected person does not get tested and treated, the infection can spread in their bodies causing irreversible damage to their reproductive organs and can lead to infertility. Chlamydia will get worse if untreated even if a person never experiences symptoms.


If you are thinking about becoming sexually active or already are, it’s important to get tested. Because Chlamydia does not always show symptoms, it can be really difficult to know when someone is infected. Teen Clinic tests for Chlamydia by either a swab or most commonly through a urine sample.  It’s that simple! Results are available within a week or two.


Chlamydia is curable and treatable with antibiotics. It’s important to finish the entire course of medication, even if symptoms go away.  It is also important for someone to refrain from any sexual contact for 7 days so reinfection does not occur.
