Chlamydia is passed on through unprotected sex or direct contact between your genitals and someone else’s, even where there is no penetration or ejaculation. 

You can catch it by sharing sex toys that are not washed between use or covered with a condom, and by getting infected semen or vaginal fluid in your eye.  

It’s also possible for a pregnant woman to pass it onto her baby.
