Learn About Chlamydia
Chlamydia is an infection caused by the bacteria Chlamydia trachomatis. It is most often spread through sexual contact.
Chlamydia trachomatis; C trachomatis; Chlamydia infection; Chlamydial infection
Both males and females may have chlamydia. However, they may not have any symptoms. As a result, you may become infected or pass the infection to your partner without knowing it.
You are more likely to become infected with chlamydia if you:
- Have sex without wearing a male or female condom
- Have more than one sexual partner
- Use drugs or alcohol and then have sex
- Have been infected with chlamydia before
In men, chlamydia may cause symptoms similar to gonorrhea. Symptoms may include:
- Burning feeling during urination
- Discharge from the penis or rectum
- Tenderness or pain in the testicles
- Rectal discharge or pain
Many men with chlamydia have no symptoms.
Symptoms that may occur in women include:
- Burning feeling during urination
- Painful sexual intercourse
- Rectal pain or discharge
- Symptoms of pelvic inflammatory disease (PID), salpingitis (inflammation of the fallopian tubes), or liver inflammation similar to hepatitis
- Vaginal discharge or bleeding after intercourse
Many women with chlamydia have no symptoms.
The most common treatment for chlamydia is an antibiotic.
Both you and your sexual partners must be treated. This will ensure that you do not pass the infection back and forth. A person may become infected with chlamydia many times.
You and your partner are asked to abstain from sexual intercourse during the time of treatment.
A follow-up may be done in 4 weeks to see if the infection has been cured.

If chlamydia spreads into your uterus and fallopian tubes, it can cause scarring. Scarring can make it harder for you to get pregnant.
You can help prevent infection with chlamydia by:
- Finishing your antibiotics when you are treated
- Making sure your sexual partners also take antibiotics
- Talking to your provider about being tested for chlamydia
- Going to see your provider if you have symptoms
- Wearing condoms and practicing safer sex
Contact your provider if you have symptoms of chlamydia.
Many people with chlamydia may not have symptoms. Therefore, many sexually active adults should be screened for the infection yearly. Check with your provider about what is best for you.
Summary: The goal of this clinical trial is to learn if point-of-care tests (POCTs) for sexually transmitted infections (STIs) improve the timely treatment of syphilis, chlamydia, gonorrhea, and trichomonas in pregnant women. It will also learn about the feasibility, acceptability, and cost-effectiveness of implementing POCTs in a large safety-net hospital setting. The main questions it aims to answer are:...
