目的了解丰城市肾综合征出血热流行特征,为制定防制措施提供科学依据。方法采用描述流行病学方法,对1965年以来的疫情资料进行分析;利用圆形分布分析发病季节性。结果 1965-2014年全市共报告病例15273例,死亡637例,年平均发病率为28.81/10万,死亡率1.20/10万,病死率4.17%。50年来,该市疫情共呈现70年代和八十年代两次发病高峰,八十年代流行强度最高。该病的季节分布显示发病集中在11月-次年1月和4-6月份。发病职业以农民发病占80%以上。男性发病高于女性。发病以20~49岁人群为主。结论该市肾综合征出血热疫情呈现七十、八十年代高发流行,九十年代之后逐年下降至低谷,近年重新抬头的态势,且病例分布在历年低发地区。必须加强疫情监测、灭鼠和疫苗接种工作来降低该病的发病率。
Objective To understand the epidemiological characteristics of hemorrhagic fever with renal syndrome in Fengcheng City and provide a scientific basis for making prevention and control measures. Methods Descriptive epidemiological methods were used to analyze epidemic data since 1965; seasonal distribution was analyzed by circular distribution. Results A total of 15 273 cases were reported in the city from 1965 to 2014, with 637 deaths.
