A50-A64: Infections with a predominantly sexual mode of transmission
A56: Other sexually transmitted chlamydial diseases
The group of conditions referred to as "Other sexually transmitted chlamydial diseases" comprises infections caused by the bacterium called Chlamydia. The Chlamydia organism can cause a wide variety of health issues and is most commonly transmitted through sexual contact. It can infect several body systems, including the reproductive and urinary tracts. Common symptoms associated with these infections can include burning during urination, lower abdominal pain, genital discharge, and in women, unusual bleeding between periods. If left untreated, these infections can progress to more severe conditions such as pelvic inflammatory disease in women and epididymitis in men, both of which can lead to infertility. The diseases are often silent, with many people showing no symptoms, which contributes to its frequent spread between partners.
