目的总结青海省2000—2012年布鲁菌病（简称布病）监测资料，评价疫情动态，分析流行趋势。方法收集2000—2012年青海省32个县的布病监测资料，采用描述流行病学的方法分析青海省人群布病的流行特征．包括患病情况、地区分布、人群分布等。结果2000—2012年，青海省共监测38578人，感染布鲁菌1290人，感染率为3．34％；患布病344人，患病率为0．89％；自2006年开始出现新发病例，共确诊新发病例158例。城市、农区、牧区的布病患病率分别为2．93％（78／2663）、1．18％（33／2806）、0．70％（233／33109）。10～72岁人群均有发病。职业人群以生物药品生产者[18．13％（196／1081）]、牧工[6．13％（353／5763）]感染率较高。民族以汉族感染率[4．61％（467／10140）]较高，其后依次为藏族[3．60％（443／12318）]、蒙古族[2．53％（211／8342）]、土族[2．22％（110／4953）]、回族[2．09％（59／2825）]，各民族比较差异有统计学意义（χ^2=102．493。P〈0．01）。结论青海省布病疫情回升，新发病例增加。

Objective By summing up monitoring data of human brucellosis in Qinghai Province from 2000 to 2012, to evaluate epidemiological dynamics and analyze prevalence trend. Method Monitoring data of human brucellosis in Qinghai Province from 2000 to 2012 were collected, epidemiological characteristics including prevalence condition, area and population distribution were analyzed by descriptive epidemiology method. Results Totally 38 578 persons were examined from 2000 to 2012. The number of persons infected with brucellosis was 1 209, the infection rate Was 3,34%; the number of patients diagnosed with human brucellosis was 344, the prevalence rate was 0.89%. New cases had occurred since 2006, and there were 158 new cases diagnosed with brucellosis. The prevalence rates in cities and areas of agriculture and pasture were 2.93% （78/2 663）, 1.18% （33/2 806） and 0.70% （233/33 109）, respectively. The ages of developing brucellosis ranged from 10 to 72 years old. The prevalence rates of biological pharmaceutical producers and the herdsman were [18.13%（196/1 081）] and [6.13%（353/5 763）], respectively. The prevalence rate of human brucellosis in Han nation was the highest [4.61% （467/10 140）], followed by Tibet [3.60% （443/12 318）], Mongolia [2.53% （211/8 342）], Tu [2.22% （110/4 953）] and Hui [2.09% （59/2 825）], and the differences were statistically significant （χ^2= 102.493, P 〈 0.01）.
