全球生殖道沙眼衣原体感染的流行状况

The global epidemic of urogenital infection with Chlamydia trachomatis

泌尿生殖道沙眼衣原体(Chlamydia trachomatis,CT)感染不仅可以引起一系列并发症,而且可以增加艾滋病传播和发生宫颈癌的风险。全球每年的CT感染新发病例超过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300/10万~550/10万,人群感染率低于2%。发展中国家人群的感染率较高。世界各国高危人群的感染率均较高。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和其他发展中国家控制CT感染的重要策略。

Urogenital infection with Chlamydia trachomatis(CT)not only causes a series of complications but also relates to significantly increased HIV transmission and cervical cancer risks.It is estimated that there are more than 100 million new cases with CT worldwide.And the Western Pacific Region in which China is located has the largest number of cases.In some developed countries,the annual reported incidence rate ranges from 300/100000 to 550/100000 and population prevalence rate is below 2%.Prevalence of CT infection in developing countries is usually higher than that in developed countries.Infection rates among high-risk groups are high across all countries.It has been indicated that active and early screening for CT infection followed by timely treatment of the infected cases,in addition to intensive behavioral interventions,should be important strategies to control the CT infection in China and other developing countries.
