摘要: 目的 探讨福建省2011-2015年人间布鲁氏菌病疫情状况,为制定预防控制策略提供科学依据。方法 对福建省卫生机构2011-2015年通过全国疾病监测系统报告的布鲁氏菌病例数据进行分析。结果 福建省布鲁氏菌病报告数由2011年的15例增加到2015年的115例,五年间共报告249例,发病率为0.13/10万,呈快速上升态势(Z=10.45,P<0.001)。漳州和南平发病率居前,分别为0.42/10万和0.18/10万。区县数由2011年的10个增加到2015年的37个(Z=25.86,P<0.001)。农村和城市发病率分别为0.29/10万和0.03/10万,均呈逐年上升态势。5~8月份为发病高峰期。男性发病率(0.19/10万)大于女性(0.07/10万)(χ2=57.27,P<0.001)。60~岁组发病率最高,为0.40/10万。农民和牧民是高发人群,占比65.46%。诊断时间小于7 d的病例占比30.52%,近5年间诊断时间趋势无统计学意义(Z=2.19,P=0.701)。福建省2011-2015年共报告14起布病突发事件,发病23人,无死亡病例。结论 福建省布鲁氏菌病疫情逐年趋于严峻,医疗机构诊断不及时,误诊较多,相关部门应根据流行特征采取有效的预防控制措施。Abstract: Objective To explore epidemic features of human brucellosis in Fujian Province from 2011 to 2015 and to provide scientific basis for the development of strategies for the prevention and control of human brucellosis. Methods The data of human brucellosis that reported by health institutions through national disease surveillance in Fujian Province, 2011-2015, were analyzed descriptively. Results The number of brucellosis cases reported increased from 15 in 2011 to 115 in 2015, and total 249 cases were reported in these five years with an incidence rate of 0.13/100 000, which also increased rapidly year by year(Z=10.45, P<0.001). Incidence rate in Zhangzhou (0.42/100 000) and Nanping (0.18/100 000) were higher than that in other regions. The number of districts in which brucellosis were reported from 10 in 2011 to 37 in 2015 (Z=25.86, P<0.001). Incidence rate of rural and country were 0.29/100 000 and 0.03/100 000, respectively, and increased significantly in these years. The incidence of brucellosis peaked from May to August. The incidence in males (0.19/100 000) was significantly higher than that in females (0.07/100 000)(χ2=57.27, P<0.001). The highest incidence was in 60 age group with 0.40/100 000. Farmers and herdsmen were high-risk population, accounting for 65.46% of total cases. 30.52% cases were diagnosed in less than 7 days and no significant decrease trend was observed in these years (Z=2.19,P=0.701). During 2011-2015, 14 brucellosis outbreaks were reported in Fujian Province, of which 23 people were infected without reported death. Conclusions Epidemic situation of brucellosis remained a serious public health issue in Fujian Province due to the lack of timely and accurate diagnosis. Therefore, the relevant departments should take effective measures to prevent and control this disease.
