Chlamydia cannot kill you.

Nonetheless, if chlamydia is left untreated, it can cause damage -- particularly to a woman's reproductive organs. It's very simple to treat and cure chlamydia with a short course of antibiotics.

A Common Sexually Transmitted Disease

Chlamydia is a common sexually transmitted disease (STD) caused by the bacterium Chlamydia trachomatis. Chlamydia can be transmitted during vaginal, anal or oral sex, and it can affect both men and women.

Even though symptoms of chlamydia are usually mild (or are completely absent), serious complications that cause irreversible damage, including infertility, can occur "silently" before a woman ever recognizes a problem.

In women, untreated chlamydia can progress to serious reproductive and other health problems with both short-term and long-term consequences. For example, the infection can spread into the uterus or fallopian tubes and cause pelvic inflammatory disease (PID). This happens in about 10 to 15 percent of women with untreated chlamydia, and can result in serious complications (including infertility, ectopic pregnancy and long-term abdominal pain).

In men, serious complications are rare.

It's very simple to treat and cure chlamydia with a short course of antibiotics. It's recommended to take the treatment as soon as you know you have the infection.
