目的了解辽宁省2012-2015年布鲁氏菌病(布病)疫情动态,研究流行规律,寻找防制工作重点,为制定防制策略提供参考。方法收集2012-2015年布病报告发病信息和监测数据,采用描述性流行病学方法进行对比分析。结果 2012-2015年辽宁省共报告布病病例9 247例,年发病率为3.37/10万~6.65/10万;非职业人群占12.46%;职业人群监测平均阳性率6.29%;病原学监测分离到136株布鲁氏菌,其中羊种Ⅰ型32株、羊种Ⅲ型103株、羊种变异型1株。结论辽宁省布病处于流行高峰,人间布病疫情由染疫的羊引起,且转为食源性等非传统传播途径的趋势增加,布病控制应加强多部门合作,采取综合性防制措施。
Objective To understand the epidemic situation of brucellosis (brucellosis) in Liaoning Province from 2012 to 2015, to study the epidemic law, to find the key points of prevention and control and to provide a reference for the formulation of prevention and control strategies. Methods The incidence and monitoring data of brucellosis from 2012 to 2015 were collected and compared by descriptive epidemiological method. Results A total of 9 247 cases of brucellosis were reported in Liaoning Province from 2012 to 2015, with an annual incidence rate of 3.37 / 100 000 to 6.65 / 100 000. The non-occupational population accounted for 12.46%. The average positive rate of occupational population surveillance was 6.29% To 136 strains of Brucella, of which 32 were sheep type I, 103 sheep type III and 1 sheep variant. Conclusion The prevalence of brucellosis in Liaoning Province is at the peak of the epidemic.
