Abstract: 【Abstract】 Chlamydia trachomatis urogenital infection can initially cause cervicitis in women and urethritis in men, and then lead to severe complications in the upper reproductive tract, such as prostatitis, epididymitis, pelvic inflammatory disease, etc., resulting in serious consequences such as ectopic pregnancy and infertility. Maternal infection is associated with serious adverse outcomes in neonates, such as preterm birth, low birth weight, and pneumonia. Due to the silent persistence of infection, many infected people go undetected and untreated. In order to improve the understanding, diagnosis and treatment of this disease among clinicians in China, the Chinese Society of Dermatology, National Center for STD Control of Chinese Center for Disease Control and Prevention, China Dermatologist Association, and Chinese Association Rehabilitation of Dermatology convened relevant experts to develop this guideline after thorough discussions and repeat revisions according to recent literature in China and other countries. This guideline summarizes epidemiological changes, clinical manifestations and classification, evidence and recommendations for the diagnosis and treatment of, as well as follow-up and cure assessment criteria for Chlamydia trachomatis urogenital infection, aiming to provide suggestions and references for medical workers at all levels.
