Abstract: Objective To analyze the epidemiological characteristics and sources of infection of human brucellosis, as well as the incidence of brucellosis among high-risk occupational populations, in Miyun district of Beijing, China, from 2013 to 2015, and to provide a basis for the prevention and control of brucellosis. Methods All brucellosis cases reported in Miyun district of Beijing from 2013 to 2015 were investigated, and the high-risk occupational populations were analyzed by serological epidemiology. The chi-square test was used to compare the rates between groups. Results A total of 48 brucellosis cases were reported in Miyun district from 2013 to 2017. The mean annual incidence of brucellosis was 2.00/100 000, with the peak period from April to July. There were more males than females among the reported cases. The 40-59 years old group had higher number of cases and incidence of brucellosis than other age groups. Of all cases, 77.08% were farmers, and 81.25% were infected by sheep. The serum antibody positive rate was 2.72% in the high-risk occupational populations of brucellosis in Miyun district from 2013 to 2017. Conclusion The sheep was the main source of infection for human brucellosis cases reported in Miyun district from 2013 to 2017, and the infection rate of brucellosis was relatively high in the high-risk occupational populations.

摘要: 目的 了解北京市密云区人间布鲁氏菌病(布病)病例流行病学特征、感染来源和高危职业人群感染状况,为制定布病的预防和控制措施提供依据。方法 选取密云区2013-2017年报告的布病病例进行流行病学调查,对高危职业人群进行血清流行病学调查分析;采用χ2检验进行组间率的比较。结果 2013-2017年密云区累计报告布病病例48例,年平均发病率为2.00/10万,每年4-7月为发病高峰期;报告病例男性多于女性,40~59岁年龄组病例数及发病率较高,农民发病数占总病例数的77.08%;感染动物以羊为主,占81.25%。2013-2017年密云区布病高危职业人群血清学抗体阳性率为2.72%。结论 2013-2017年密云区人间布病感染来源主要是羊,并且高危职业人群布病感染率较高。
