Question about chlamydia ❔

So we all know that chlamydia is a STD, right? Which means it's a 'sexually transmitted disease'. So, my question for everyone: is there another way to get chlamydia, without having sex? I'm asking this because a year ago, a nurse came to my school talking about the various forms of birth control and STI's/STD's. One thing I remember from her presentation is how she said that toilets (specifically public toilets) can give you chlamydia. Is this true?

Edit: thanks for answering! ^^ now I know it's okay to use public restrooms 😂
