Most cases of chlamydia occur through sexual contact with someone who has a chlamydia infection.
- You can get chlamydia by having unprotected vaginal, anal or oral sex with someone who has chlamydia.
- You can still get chlamydia even if the person you're having sex with doesn't ejaculate (cum).
- Chlamydia can also be spread through other types of sexual contact such as mutual masturbation, fingering or the use of sex toys.
- One simple way to protect yourself is by using a condom when engaging in sexual intercourse.
Another way of transmitting chlamydia is from mother to baby during birth. If this occurs, your baby may develop an eye or lung infection. This needs urgent treatment.
If you are sexually active, get regular STI checks. If you think you may have been exposed to chlamydia, see your healthcare provider for an extra STI check.
