目的掌握广州市男男性行为人群(MSM)艾滋病流行特征和趋势,为制定与落实防控策略和措施提供科学依据。方法对广州市2000-2010年艾滋病病例报告、血清学横断面调查、新发感染率队列研究和疫情估计等数据进行综合整理分析。结果广州市2000年报告首例MSM病例,至2010年共报告526例,其中2008-2010年报告数占92.2%。2010年血清学监测MSM人群的HIV感染率为7.4%,较2006年的1.3%显著增加。2009-2010年MSM队列研究HIV发病密度为3.2/100人年。2009年疫情估计广州市MSM规模约34 810~61 616人,存活的MSM感染者约有1 666人。结论广州市2000-2010年MSM人群艾滋病感染人数呈逐年增加的趋势,但发现比例较小,亟需加强该人群的动员检测工作力度,提高病例发现率,并加强病例管理,阻断二代传播。
Objective To understand the characteristics and trends of HIV / AIDS in MSM in Guangzhou and to provide a scientific basis for formulating and implementing prevention and control strategies and measures. Methods The data of AIDS cases, serological cross-sectional survey, new cohort infection rate and epidemic situation of Guangzhou City from 2000 to 2010 were analyzed. Results The first case of MSM was reported in 2000 in Guangzhou City. By 2010, a total of 526 cases were reported, of which 92.2% were reported in 2008-2010. In 2010 serological surveillance MSM population HIV prevalence was 7.4%, significantly higher than 1.3% in 2006. 2009-2010 MSM cohort study of HIV incidence density of 3.2 / 100 person-years. The outbreak in 2009 estimated the MSM size of Guangzhou City was 34 810 ~ 61 616 people, and there were about 1 666 surviving MSM infections. Conclusions The number of HIV / AIDS patients in MSM population increased year by year from 2000 to 2010 in Guangzhou City. However, the proportion of HIV infection in MSM population is increasing year by year. However, it is urgently needed to strengthen the mobilization and detection of this population, increase the case detection rate and strengthen case management, .
