Chlamydia

Chlamydia is one of the most common STIs in the UK, around 1 in 10 young people have it. Most people who have Chlamydia don’t notice any symptoms and won’t know they have the infection.

Otherwise, symptoms may include pain when you pass urine (pee), unusual vaginal discharge, abdominal pain and in women, bleeding between periods or after sex.

Testing for Chlamydia is easily done. Chlamydia is treated with antibiotics, but can lead to serious long-term health problems if it's left untreated.
