Since Clamidia is a sexually transmitted disease that means that it is passed on through sexual intercourse whether it’s vaginally, anally or orally. Any sexually active person can be infected with Clamidia. Like most STD’s, the greater number of sex partners, the greater the risk of getting infection. Teenage girls and young women have a little higher risk of infection due to their cervix is not fully matured. Also, since Clamidia can be transmitted by oral and anal sex, men who are sexually active with men also have the risk of Clamidia infection. Clamidia can also be passed from an infected mother to her baby during vaginal childbirth.
