There are two ways chlamydia can be transmitted: (1) From one person to another by sexual contact or (2) From mother to child when the child passes through the birth canal. Tell your girfriend that all of your research consistently concludes that chlamydia cannot be "developed" (feel free to show her this message and other websites) and that it would be irresponsible if she didn't notify the other infected partner.
