目的根据日照市2010-2013年肾综合征出血热(HFRS)的疫情资料,分析HFRS流行特征和变化趋势。方法采用描述性流行病学方法和圆形分布对资料进行分析。结果 2010-2013年日照市累计报告HFRS病例633例,死亡5例,年均发病率为5.65/10万。HFRS发病有明显地季节性,9~12月为主要流行季节。各区县东港区发病数最高。30~69岁的男性农民发病占大多数。2010-2013年HFRS实验室诊断比例显著提升,4年间实验室诊断率的差异具有统计学意义(χ2=149.20,P<0.05)。结论日照市肾综合征出血热的主要传染源为姬鼠。农村是出血热的重点防控地区,男性青壮年农民是HFRS的高发人群。日照市各级医疗机构开展HRFS的实验室检测比例和检测准确率逐步上升。
