泌尿生殖道沙眼衣原体感染已经成为世界范围内最常见的性传播感染,不仅可以引起一系列并发症,而且可以促进艾滋病传播和增加宫颈癌的发病风险。全球每年的新发病例超过1亿,以我国所在的西太平洋区域发病数最高。据部分发达国家的监测系统报告,年报告发病率为300/10万~450/10万,我国由于受到主动检测和检测手段的局限,报告发病率低于发达国家,但人群感染率较高,特别是高危人群的感染率高达5%~17%。因此,在加强行为干预的同时,开展CT感染的主动早期筛查和及时有效的治疗是我国控制CT感染的重要策略。 Urogenital Chlamydia trachomatis infection has become the world’s most common sexually transmitted infection, not only can cause a series of complications, but also can promote the spread of AIDS and increase the risk of cervical cancer. More than 100 million new cases occur each year globally, with the highest incidence in the western Pacific region where our country is located. According to some developed countries’ monitoring system reports, the annual report incidence rate is 300 / 100,000 to 450 / 100,000. Due to the limitation of active detection and detection methods in our country, the reported incidence is lower than that in developed countries, but the infection rate in the population is high, In particular, the infection rate of high-risk groups as high as 5% to 17%. Therefore, in strengthening behavioral interventions, active early screening for CT infection and prompt and effective treatment of CT infection is an important strategy in our country.
