Chlamydia is an infection caused by the bacteria Chlamydia trachomatis. It is the most common sexually transmitted infection in the United States, with 4 million new cases each year. It is especially prevalent among teenagers and young adults. It frequently occurs along with gonorrhea infections (one-fourth of men and two-fifths of women with gonorrhea also have chlamydia).

Symptoms: may not appear for long periods of time, or may never appear

In Men: painful burning sensation during urination, watery or milky discharge from the penis

In Women: abnormal vaginal discharge, irregular vaginal bleeding, pelvic pain accompanied by nausea and fever, painful or frequent urination

Women are less likely to exhibit any symptoms at all; therefore, it is important to have bacterial culture tests done during pelvic exams if you suspect that you might be infected.

Treatment: antibiotics such as doxycycline or tetracycline

If Untreated: women can develop pelvic inflammatory disease and other infections that can lead to the loss of the ability to have children.
