Chlamydia is a Sexually Transmitted Infection (STI).You get it by having unprotected penetrative or oral sex with an infected person. If you have it, you are 5 times more likely to get HIV. About half the people who get chlamydia become infertile if they are not treated quickly. It is easy to treat but you can have it without your body showing signs. So, if you had sex without a condom, get tests and treatment at a clinic IMMEDIATELY to be sure. ALL sex partners must be treated or you will get infected again.
