2016-2020年辽宁省人间布鲁氏菌病流行特征分析

Epidemiological characteristics of human brucellosis in Liaoning province,2016-2020

目的了解2016—2020年辽宁省人间布鲁氏菌病(布病)流行动态及规律,为制定和完善防控策略和措施提供参考依据。方法收集辽宁省2016—2020年人间布病报告确诊病例和重点职业人群监测信息,描述、分析其三间分布情况和监测结果。结果2016—2020年全省14个市累计报告人间布病确诊病例11569例,死亡1例。发病高峰为3—8月,病例主要集中在40~64岁,且以农民为主。重点职业人群监测工作中,流行病学调查68804人,血清学检测32559人,阳性1708例,阳性率为5.25%。病原学检测布病样本830份,分离出羊种布鲁氏菌210株。结论辽宁省布病发病数和发病率总体呈上升趋势,且2020年发病数和发病率创历史新高。人间布病流行态势错综复杂,布病防控形势严峻,防控策略和措施需要进一步优化和完善。

Objective To analyze the epidemic dynamics and regularity of human brucellosis in Liaoning province from2016 to 2020,and provide scientific evidence for the formulation and improvement of prevention and control strategies and measures,so as to reduce the loss caused to national health and economy.Methods The data that the confirmed human brucellosis cases and the surveillance information of key populations with occupational exposure in Liaoning province from2016 to 2020 were collected to describe and analyze three-dimension distribution and surveillance results.Results A total of 11569 confirmed human cases and 1 death were reported in 14 cities of Liaoning province during the study period.The peak incidence of brucellosis was March to August,and the disease were mainly found focused on 40 to 64 years old people,mainly in farmers.In the monitoring of key populations with occupational exposure,epidemiological investigation included 68804 people,among which 32559 were tested serologically,and 1708 were positive,with a positive rate of 5.25%.Total of 830 samples were detected by etiology,and 210 strains of Brucella were isolated.Conclusion The cases and incidence of brucellosis in Liaoning province increased year by year and reached a record high in 2020.The epidemic situation of human brucellosis is complicated,and the prevention and control situation of brucellosis is very grim.The strategies and measures need to be further optimized and improved.
