目的了解北湖区高危人群中艾滋病流行趋势及危险因素,有效监测该区艾滋病性病流行现状及艾滋病相关行为随时间的变化趋势,为评价艾滋病预防与控制效果提供依据。方法2009年在该区分别对402名暗娼、406名吸毒者进行HIV哨点监测,应用酶联免疫吸附试验(ELISA)对样本进行HIV筛查。结果2009年,暗娼主要为未婚的本省户籍者,安全套使用率为88.56%,13.68%的暗娼为吸毒者,无静脉吸毒史,检出HIV抗体阳性1例,感染率为0.25%;吸毒人群主要为未婚的本省户籍者,安全套使用率为31.78%,90.89%采用静脉吸毒,90.82%最近六个月共用过注射器,检出HIV抗体阳性者5例,感染率为1.23%。结论该区艾滋病的流行仍处于低流行状态,暗娼不使用安全套,吸毒者共用注射器等不安全行为仍广泛存在,提示应加强对高危人群的宣传,加大监测力度,进一步采取有效预防措施提高行为干预的覆盖率,控制艾滋病的传播与蔓延。
Objective To understand the epidemiological trend and risk factors of AIDS among high-risk population in Beihu district, to effectively monitor the status quo of HIV / AIDS-related prevalence and the trend of AIDS-related behaviors over time in order to provide basis for evaluating the effectiveness of AIDS prevention and control.

Unmarried residents of the province, the condom use rate was 31.78%, 90.89% intravenous drug use, 90.82% shared the syringe for the past six months, detected HIV antibody positive in 5 cases, the infection rate was 1.23%. Conclusions The prevalence of AIDS in this area is still in a low prevalence status. The unsafe behaviors such as the use of condoms by sex workers and the sharing of syringes by drug users are still widespread, suggesting that publicity should be intensified for high-risk groups, monitoring efforts should be intensified, and effective preventive measures should be taken to improve behaviors Intervention coverage to control the spread and spread of AIDS.
