Yes, you can contract chlamydia more than once, although it’s rare for it to reoccur or persist after correct treatment.
There are a few reasons why you might contract chlamydia a second time:
- The initial infection wasn’t cured because the course of antibiotics wasn’t completed as directed.
- A sexual partner transmitted chlamydia to you.
- You used a sex toy that was contaminated with chlamydia.
A 2014 study suggests that chlamydia can live in the gastrointestinal tract and reinfect the genitals, causing chlamydia symptoms to reappear after the genital infection went away.
However, this study only looked at animal models of chlamydia. Research on human participants is needed.
The symptoms of chlamydia typically disappear once you finish your antibiotics. This can vary in time, as some chlamydia antibiotic courses are one dose taken on one day, while others last longer.
The CDC Trusted Source recommends waiting seven days after a one-day antibiotic, or until the end of a seven-day antibiotic course, before having partner sex again.
