Chlamydia

Chlamydia is a bacterial sexually transmitted infection (STI) that affects both men and women. It is caused by the bacterium Chlamydia trachomatis and is one of the most commonly reported STIs in the United Kingdom.

Chlamydia is primarily spread through vaginal, anal, or oral sex, and can also be transmitted from an infected mother to her baby during childbirth. The infection can cause a range of symptoms, including pain during urination, discharge from the penis or vagina, and abdominal pain in women. However, many people with chlamydia may not experience any symptoms at all, making it difficult to know if they have the infection.

If left untreated, chlamydia can cause serious health problems, including pelvic inflammatory disease (PID) in women, which can lead to infertility. In men, chlamydia can also cause epididymitis, a painful condition that affects the testicles.

Chlamydia can be easily treated with antibiotics. It is important to get tested if you have had unprotected sex or suspect you may have an STI, as chlamydia can be easily passed on to others. Regular testing and prompt treatment are important for maintaining sexual health and preventing the spread of STIs.
