Chlamydia is one of the most common sexually transmitted infections (STIs) in the United States. Millions of new cases occur each year, and many people don’t realize they have it because symptoms are often mild—or completely absent. Left untreated, chlamydia can affect reproductive health and lead to serious complications.

What Is Chlamydia?

Chlamydia is a common bacterial sexually transmitted infection (STI) caused by Chlamydia trachomatis. It is one of the most frequently reported STIs in the United States and often spreads without noticeable symptoms, which is why routine testing is so important.

Chlamydia can infect the genitals, rectum, and throat and is easily treated with antibiotics when diagnosed early. If left untreated, it can lead to serious complications, including infertility.

How these common STIs differ in symptoms, testing, and treatment

Chlamydia, gonorrhea, and trichomoniasis are among the most common sexually transmitted infections (STIs) worldwide. Because they can cause similar symptoms — or no symptoms at all — they are often confused with one another.

Understanding how they differ helps ensure proper testing, treatment, and prevention.
