Results of serological monitoring of human brucellosis from 2009 to 2013 in Ruzhou city

目的分析汝州市人间布鲁氏菌病（简称布病）血清学监测结果,了解汝州市布鲁氏菌病的流行现状及特征,为制定防控策略提供依据。方法按照《布鲁氏菌病诊断标准》对2009~2013年到汝州市疾控中心就诊的疑似病例进行血清学监测。结果汝州市共检测标本2 573例,1 124例为阳性,阳性率为43.68%;发病有明显的季节分布,5月份为人间布病发病高峰;男性与女性阳性率比约为2.44：1（797/327）,性别间差异有统计学意义（P〈0.01）;〉50岁年龄组阳性率最高（49.44%,620/1 254）,不同年龄组间阳性率差异有统计学意义（P〈0.01）;职业分布以农民感染率为最高（94.57%,1 063/1 124）,不同职业间阳性率差异有统计学意义（P〈0.01）。结论汝州市布鲁氏菌病疫情呈上升趋势,应加强畜间管理,开展重点职业人群布病防治知识健康教育,降低其发病水平。

Objective To analyze the results of serological monitoring of human brucellosis and its epidemiologicalfeatures in Ruzhou city, so as to provide evidence for control and prevention strategies.Methods Serological detection wasconducted among suspected brucellosis cases in Ruzhou city from 2009 to 2013 and the test results were judged according to＂Diagnostic standard for brucellosis＂. Results Totally 2 573 suspected brucellosis cases were detected and 1 124 positiveswere found, with the total positive rate of 43.68%. Distinct seasonal distribution was observed and May was the epidemic peakof human brucellosis.The ratio of male patients to female patients was 2.44 to 1（797/327）,approximately. The highest positiverate was observed in age group of over 50 years（55.17%,620/1 254）. There were significant statistical differences betweendifferent age groups（P〈0.01）.The human brucellosis mainly occurred among famers.There were significant statisticaldifferences in positive rate between different occupations（P〈0.01）. Conclusion Human brucellosis incidence showed anuprising trend in Ruzhou city.Thus the management of livestock husbandry should be strengthened and health educationtargeted at high-risk groups should be carried out to reduce the incidence of brucellosis.
