Can You Get Chlamydia Without Having Sex?

Chlamydia is, for practical purposes, a sexually transmitted infection — the overwhelming majority of cases are acquired through vaginal, anal, or oral sex. There's one genuine, well-documented non-sexual exception worth knowing about.

The real exception: mother-to-newborn transmission

A pregnant person with an active chlamydia infection can pass it to their newborn during vaginal delivery, potentially causing conjunctivitis (eye infection) or, less commonly, pneumonia in the infant. This is exactly why prenatal STD screening, including chlamydia, is a standard part of pregnancy care — catching and treating it before delivery prevents this transmission route entirely.

What isn't a realistic route, despite persistent claims

Toilet seats, shared towels, swimming pools, and casual contact are not realistic chlamydia transmission routes — the bacteria doesn't survive well outside the body and requires direct mucous membrane contact to establish an infection. Claims to the contrary circulate periodically online but aren't supported by how the bacteria actually behaves.
