To analyze the epidemiological characteristics of human brucellosis in northern and southern areas of China, and to develop national strategies for brucellosis prevention and control. Individual data on human brucellosis was collected from the National Notifiable Infectious Disease Reporting Information System to describe the situation of brucellosis in China during 2015-2016. Epidemiological features of the disease in northern and southern areas of China were analyzed. A total of 104 125 cases were reported in mainland China during 2015-2016, with an average incidence rate as 3.81/100 000. The overall incidence rate from the northern provinces was 7.77/100 000 in 2016, a 18.6 decrease from 2015 (9.55/100 000), whereas the incidence rate in the southern provinces was 0.27/100 000 in 2016, with an increase of 28.6 than 0.21/100 000 in 2015. 90.0 of the newly infected counties mainly distributed in southern China. As for the locations of reporting cases, most of them were in the same counties in the northern areas (52.3) while most cases in the southern areas (59.6) were imported from other counties. The median age of the cases was 48 ( 38-58) years, with male-to-female ratios as 2.7∶1 in the north and 2.2∶1 in the south. Majority of the cases were occupation-related, from both the northern (86.8) and southern (62.7) areas. Human brucellosis occurred every month throughout the year but with an obvious seasonal increase between March and July. Different epidemiological features of human brucellosis appeared in both northern and southern areas of China. The disease was seen endemic in the northern and dispersal in the southern provinces. Appropriate strategies for brucellosis prevention and control should be developed, according to the different epidemiological characteristics in the northern or southern areas.
分析中国南北地区人间布鲁氏菌病的流行病学特征，制定全国布鲁氏菌病防控策略。从国家法定传染病报告信息系统收集人间布鲁氏菌病的个体数据，以描述2015 - 2016年中国布鲁氏菌病疫情状况。分析中国南北地区该病的流行病学特征。2015 - 2016年中国大陆共报告104125例病例，平均发病率为3.81/10万。北方省份2016年的总发病率为7.77/10万，较2015年（9.55/10万）下降了18.6%；而南方省份2016年发病率为0.27/10万，较2015年的0.21/10万增长了28.6%。新增感染县的90.0%主要分布在中国南方。就报告病例的地点而言，北方大多数病例（52.3%）发生在同一县内，而南方大多数病例（59.6%）是从其他县输入的。病例的中位年龄为48（38 - 58）岁，北方男女比例为2.7∶1，南方为2.2∶1。大多数病例与职业相关，北方（86.8%）和南方（62.7%）均如此。人间布鲁氏菌病全年每月均有发生，但在3月至7月间季节性明显增加。中国南北地区人间布鲁氏菌病呈现出不同的流行病学特征。该病在北方呈地方性流行，在南方呈散发状态。应根据南北地区不同的流行病学特征制定相应的布鲁氏菌病防控策略。
