Chlamydia

Chlamydia is one of the most common sexually transmitted infections (STIs) in the UK. It’s caused by bacteria and often has no symptoms, which means many people don’t realise they have it. If left untreated, it can lead to serious health problems, including infertility. Thankfully, it is easily tested for and treated with antibiotics.

What is Chlamydia?

Chlamydia is an infection that spreads through unprotected vaginal, anal or oral sex, or by sharing sex toys without proper cleaning. It affects both men and women and is most common in people under 25. You can get tested even if you don’t have symptoms, and testing is free on the NHS.
