Because chlamydia rarely causes symptoms, most individuals who have it are unaware of it until it damages their sexual health. One of the most prevalent STIs in the UK is chlamydia. It is found mainly in sexually-mature teenagers as well as young adults. It is transmitted through unprotected intercourse (unprotected sex) that takes place without the use of a condom or another barrier contraceptive.
