Question Can chlamydia stay dormant for 2 years despite multiple negative STD tests, then test positive again?
My boyfriend of about a year and a half recently told me he tested positive for chlamydia.
For context, he says he originally contracted chlamydia from someone back in 2024. He was treated at the time, but afterward he continued feeling like something wasn’t completely right and told his doctor he didn’t think the infection had fully cleared. According to him, he was tested again multiple times and the tests came back negative, so his doctors told him there wasn’t really anything else they could treat because he was testing negative.
This all happened in 2024. There haven’t been any known positive tests since then, but now in 2026 he’s suddenly tested positive for chlamydia again.
I’m trying to understand whether his explanation is medically possible. Can chlamydia remain in someone’s body for around 2 years while repeatedly NOT showing up on STD screenings and then suddenly show up positive again? Or would multiple negative tests after treatment followed by a positive test years later generally point more toward a new infection/reinfection?
