目的分析2006—2015年山西省布鲁氏菌病(布病)疫情特征,为开展布病预防与控制提供依据。方法对山西省10年间报告的布病数据资料进行描述性分析。结果 10年间山西省共报告布病54 679例,呈逐年增加趋势,由2006年的3452例增至2015年的6997例,平均增幅为10.27%;病例波及全省11市119个县(市、区),2011-2015年扩散至山西省所有县(市、区),报告发病率介于10.26/10万~23.53/10万之间,平均发病率为15.51/10万;2014年发病数、发病率均达到有记录以来的最高水平,大同市、朔州市、晋中市和忻州市共报告布病37 619例,占全省报告病例总数的68.80%。布病监测点共采集职业人群血清25 190份,阳性2068人,阳性率为8.21%。全省共分离到布鲁氏菌226株,羊种布鲁氏菌225株,布鲁氏菌非典型菌株1株,羊种3型布鲁氏菌225株,占总分离菌株数的99.56%。结论山西省近年来布病发病呈快速上升趋势,大同市、朔州市和晋中市布病流行水平较高,运城市和临汾市疫情增长较快,呈明显的季节性高发特征。布鲁氏菌流行优势菌种是羊种3型,应进一步加强布病防治,控制布病疫情。
Objective To analyze the epidemic characteristics of brucellosis (brucellosis) in Shanxi Province from 2006 to 2015 and provide the basis for the prevention and control of brucellosis. Methods Descriptive analysis of brucellosis data reported in Shanxi Province over the past 10 years was carried out. Results A total of 54 679 cases of brucellosis were reported in Shanxi Province over the past 10 years, showing an increasing trend year by year, from 3452 cases in 2006 to 6997 cases in 2015, an average increase of 10.27%. Cases spread to 119 counties (cities, prefectures, Area). From 2011 to 2015, it spread to all counties (cities and districts) in Shanxi Province. The reported incidence ranged from 10.26 / lakh to 23.53 / lakh and the average incidence rate was 15.51 / lakh. In 2014, The incidence rate reached the highest level since records were recorded. 37,619 cases of brucellosis were reported in Datong, Shuozhou, Jinzhong and Xinzhou, accounting for 68.80% of the total reported cases in the province. A total of 25 190 serum samples from the occupational population were collected from the cloth disease surveillance sites, with 2068 positives, the positive rate was 8.21%. In the province, 226 strains of Brucella, 225 strains of Brucella abortus, 1 strain of Brucella atypical and 225 strains of Brucella in sheep were isolated, accounting for 99.56% of the total isolates, . Conclusions The incidence of brucellosis in Shanxi Province has been increasing rapidly in recent years. The prevalence of brucellosis in Datong, Shuozhou and Jinzhong is high, and the outbreaks in Yuncheng and Linfen are increasing rapidly with obvious seasonal high incidence. The prevalence of brucellosis species is sheep species 3, brucellosis should be further strengthened to prevent and control brucellosis.
