Chlamydia is one of the most common sexually transmitted infections (STIs) in the UK. You’re more likely to be infected if you’re under 25 and sexually active, but it can affect anyone. Though it’s easy to treat, it’s largely symptomless and often goes undetected. 

Left untreated, chlamydia can cause long-term complications, particularly in women.
