目的了解2011-2015年贵州省艾滋病流行特征,为制定预防控制措施提供依据。方法利用艾滋病综合防治信息系统数据资料,用描述流行病学方法分析2011-2015年艾滋病新发病例情况。结果报告病例数逐年增加,合计报告20 005例。男女比例为2.1∶1;年龄20~49岁,占65.2%,呈下降趋势,50岁以上逐年上升;民族以汉族为主,占71.5%;职业分布农民为主,占44.9%,上升幅度最大;全省88个县(区)均有病例报告,最多的达781例,最少的23例;传播途径中异性传播和同性传播呈上升趋势,吸毒传播逐年下降,异性传播所占比例为84.4%,高年龄组病例上升幅度远大于低年龄组,同性传播主要集中在20-29岁年龄组,占56%;样本来源以医疗机构其他就诊者最多,占42.2%;筛查检测数逐年上升,阳性检出率先上升后下降。结论报告病例上升幅度有所下降,性传播已成为主要传播途径,老年感染者报告数逐年上升,流行范围广、地区差异大,流行因素复杂,防控形势严峻。
Objective To understand the characteristics of AIDS epidemic in Guizhou Province from 2011 to 2015 and provide the basis for making prevention and control measures. Methods Using the data of AIDS Integrated Prevention and Control Information System, the descriptive epidemiological method was used to analyze the new cases of AIDS in 2011-2015. The number of reported cases increased year by year, with a total of 20 005 cases reported. The ratio of male to female is 2.1: 1; the age is from 20 to 49, accounting for 65.2%, showing a downward trend and increasing from the age of 50; the ethnic group is dominated by the Han nationality, accounting for 71.5%; the main occupation is farmer, accounting for 44.9% ; The 88 counties (districts) in the province have reported cases with a maximum of 781 cases and a minimum of 23 cases. The frequency of heterosexual transmission and homosexual transmission in transmission routes is on the rise. The transmission rate of drug abuse drops year by year with the proportion of heterosexual transmission accounting for 84.4% The incidence of cases of higher age group was much higher than that of lower age group. Same-sex transmission mainly occurred in the age group of 20-29 years old, accounting for 56%. The sample source was the largest in other medical institutions (42.2%). The number of screening tests increased year by year, Positive detection rate rose first and then decreased. Conclusions The increase rate of reported cases has decreased. Sexual transmission has become the main route of transmission. The number of reported cases of senile infections has been increasing year by year with a wide range of epidemic, large regional differences, complicated epidemic factors and severe prevention and control.
