Transmission of Chlamydia

Chlamydia is spread by infected semen and vaginal secretion during unprotected sexual activity, including vaginal sex, anal sex, oral sex and sharing of unwashed sex toys with an infected person. Chlamydia can also be spread from the infected mother to the baby during childbirth (neonatal chlamydial infection), leading to infection of the newborn’s eyes, ears and lungs.

Incubation period: 7 to 14 days

Prevention

Chlamydia can be prevented by using condoms correctly and consistently during vaginal, anal and oral sex. You should not share sex toys with others if they are unwashed between use.
