Great question! Chlamydia is a bacterial infection spread through semen and vaginal fluid. It is not transmitted by blood or skin-to-skin contact.
The best way to prevent chlamydia is by abstaining from oral, anal, and vaginal sex. If you do choose to be sexually active, using barrier methods like condoms and dental dams can reduce the risk of transmission. Asking your partner to get tested before you become sexually active is also a great idea! Chlamydia testing is free or low-cost and confidential at Teen Clinic, and you can get tested on a walk-in basis.
