What is chlamydia?

Chlamydia is a sexually-transmitted disease (STD) that affects both men and women. It is a very common condition; in fact, it is the most common STD in the U.S.

How often do chlamydia symptoms appear?

One reason that chlamydia is so common is that the majority of infected people do not have symptoms. This is referred to as a “silent” infection. This means they can unknowingly spread the infection to their sex partners. The U.S. CDC recommends that sexually active women under 25 years of age be tested for chlamydia every year, because it can damage the reproductive tract, causing infertility when untreated. Once the infection has been identified, treatment is simple and effective. It is also recommended that pregnant women be tested as well as women with multiple or new sex partners.

Men who are infected sometimes also notice an abnormal discharge or burning with urination. Pain or swelling in the testicles is possible in infected men, but this is not a common symptom.

Symptoms of PID can include:
