2005-2016年全国布鲁氏菌病监测数据分析

我国从1980年开始开展布鲁氏菌病（布病）主动监测，2005年将布病纳入全国重点传染病监测工作，在全国19个省（自治区、直辖市）设定21个固定监测点开始人间布病监测。本文就中国疾病预防控制中心2005-2016年年度布鲁氏菌病监测报告进行汇总分析。2014年全国布病疫情报数为告历史最多，人间新发布病57 222例，发病率为4.22/10万；布病疫情由2005年18个省份报告布病病例，至2013年增加到31个省份。布病病例职业分布涉及到所有分类。12年来21个监测点开展职业人群调查573 032人，血清学检查196 636人，检出阳性39 190例，平均阳性率为18.11%。监测点检菌164株，结合部分送检菌株，在全部276株菌中，羊种布鲁氏菌占74%，还有16%菌株待鉴定，说明引起我国布病疫情的优势菌株是羊种布鲁氏菌。

Surveillance data of brucellosis in China,2005-2016

Active surveillance for brucellosis started in 1980 in China and has been included in the national priority communicable disease surveillance since 2005. Brucellosis Surveillance is conducted in 21 permanent surveillance areas in 19 province(autonomous region,municipality). This paper summarizes the annual surveillance report of brucellosis in China (2005-2016)by Chinese Center for Disease Control and Prevention. In 2014,the reported case number of human brucellosis was highest in the history(57 222 cases),the morbidity rate was 4.22/100 000. The disease was only reported in 18 provinces (autonomous region,municipality)in 2003,but reported in all 31 provinces(autonomous region,municipality)in 2013. Brucellosis affected all the populations with occupational exposure. A total of 573 032 persons with occupational exposure were surveyed in 21 surveillance areas during the past 12 years,and serological test was performed for 196 636 persons,in whom 39 190 were sero-positive. The average positive rate was 18.11%. A total of 276 Brucella strains were analyzed,including 164 strains detected in surveillance areas and some strains sent for detection. Among these strains,Brucella melitensis accounted for 74%,and 16% the remained unidentified,which indicating that B. melitensis was the predominant pathogen causing brucellosis epidemics in China.
