Abstract: Objective To understand the epidemic situation of human brucellosis in Bay county in Xinjiang Uygur Autonomous Region (Xinjiang), China in 2015 and provide the scientific basis for controlling human brucellosis in the future. Methods The data of human brucellosis were collected from all 16 towns in Bay county which had serological examination in persons with clinical symptoms and contact history from February 23 to September 18, 2015. The positive rate was compared with Chi square test. Results Serological detection was performed on 920 samples, of which 125 samples produced positive results (serum test positive rate 13.59%), the average prevalence was 12.93%, and the asymptomatic infection rate was 0.65%. Bulong and Yatur township prevalence rates were 37.50% and 33.33% respectively. The positive rate of serological test in males was 15.68%, higher than that in females 10.41% (χ²=5.198,P=0.023). The positive rates of serological test in students, herdsmen and farmers were 18.42%, 14.47%, and 14.17% respectively. Conclusion The high positive rate of serological test for brucellosis in Bay county warrants attention by the local government and the administrative departments of health. The emphases of infection populations were students, young farmers and herdsmen occupational groups, so we should carry out extensive health education about knowledge of brucellosis prevention, focusing on local schools and agricultural and pastoral areas to strengthen prevention and control measures.

摘要： 目的 分析2015年新疆维吾尔自治区（新疆）阿克苏地区拜城县人间布鲁氏菌病（布病）疫情现状和动态，为制定防治措施提供科学依据。方法 按《新疆人间布鲁氏菌病防治监测实施方案》，于2015年2月23日至9月18日对拜城县16个乡镇进行现场筛查，检测对象为与畜牧及畜产品有密切接触的人群。对有临床症状和接触史人员进行血清学检测。阳性率的比较采用χ²检验。结果 2015年共检测920人，血检阳性率为13.59%，平均患病率为12.93%，隐性感染率为0.65%；布隆乡和亚吐尔乡患病率分别高达37.50%和33.33%。平均血检阳性率男性（15.68%）高于女性（10.41%）（χ²=5.198，P=0.023），40~岁年龄组男性血检阳性率高于女性，差异有统计学意义（χ²=4.343，P=0.037）。学生、牧民和农民血检阳性率较高，分别为18.42%、14.47%和14.17%。结论 拜城县布病血检阳性率较高的重点感染人群为学生、青壮年农牧民和高危职业人群，应重点在当地学校和农牧区加强专业防控措施及高危人群的行为干预。
