Chlamydia is one of the most common sexually transmitted infections (STIs).
Anyone who has oral, vaginal or anal sex, without using a condom, can get it or pass it on.
You could have chlamydia even if you have no symptoms, or your symptoms go away.
Chlamydia is easy to treat with medical help.
If you don’t get it treated, it can lead to serious problems such as infertility.
The only way to know if you have chlamydia is to get tested.
