新疆口岸出入境人群中230例HIV感染者的流行病学调查分析

目的了解并掌握新疆口岸出入境人员艾滋病病毒（HIV）感染的情况和流行病学特征，为今后过境口岸出入境人群中艾滋病防控提供科学依据。方法对2001—2007年共291 200名出入境人员传染病监测体检中的HIV抗体阳性资料进行整理、统计分析。结果共检出HIV抗体阳性者230例，总感染率0．79‰；感染者20-40岁的占94．78％；男性占78．70％，女性占21．30％，男女比为2．2：1；少数民族感染比例高；商务人员和交通工具驾驶员为高危人群；传播途径仍然以吸毒及性传播为主。结论新疆重点区域的艾滋病流行情况并没有得到有效控制，仍在快速蔓延。因此，加强对出入境人员进行艾滋病监测，对HIV感染者进行流行病学调查、分析，加强防止艾滋病传播知识的宣传，是在过境口岸控制艾滋病传播的重要环节。

Epidemiological survey of 230 cases of HIV infection among entry-exit personnel at the Xinjiang Port

Objective To understand the infection status and epidemiological features of individuals entering and exiting the Xinjiang Port so as to provide scientific basis for the prevention and control of AIDS at various ports in China. Methods The data of HIV infection among 291 200 individuals entering and exiting the Xinjiang Port between 2001 and 2007 was analyzed. Results A total of 230 individuals were found infected with HIV and the total infection rate was 0.79‰. The people of prime age （from 20 to 40 years） were the main victims of the infection,the ratio of infection between males and females was 22 ： 1 ,and higher rate of infection was seen among the ethnic minority;and traders and drivers were the high risk group. The routes of transmissions differed from region to region, but the mian routes were drug use and sex contact. Conclusion The HIV epidemic in some highly prevalent areas of Xinjiang has not been effectively controlled, and is now being rapidly spread. Therefore, for the control of AIDS transmission at the frontier port it is crucial to strengthen AIDS surveillance among entry-exit personnel, to carry out epidemiological survey,and to disseminate knowledge of AIDS preventioical survey.
