Chlamydia typically enters a man’s body through his penis or mouth during unprotected sex with an infected partner. It can be passed through vaginal, anal, and oral sex. It can also be passed to the eye by a hand or other body part moistened with infected secretions. Chlamydia cannot be spread by kissing, toilet seats, bed linens, doorknobs, swimming pools, hot tubs, bathtubs, silverware, or sharing clothes. The best way to avoid getting chlamydia is to not have sex or to use condoms every time you have vaginal, anal or oral sex. Chlamydia is easily treated with antibiotics but can cause serious problems if left untreated, so it’s important to get tested regularly (at least once a year) if you’re having sex. There’s no other way to tell if you or your partner is infected because many people with chlamydia have no symptoms at all.
