目的分析泗洪县流行性出血热流行特征,为进一步做好流行性出血热防控工作提供依据。方法对2011—2016年上报到《中国疾病预防控制信息系统》审核确定的泗洪县流行性出血热报告病例进行分析。结果泗洪县2011—2016年累计报告流行性出血热病例121例,年均发病率为1.87/10万,2014年发病率最高(2.88/10万);南片15个乡镇发病总数38例,北片11个乡镇发病总数62例,二者发病率差异有统计学意义(χ~2=9.16,P<0.01);疫情呈明显季节性,11至12月病例数占报告病例总数61.98%;男性发病率高于女性(χ~2=25.14,P<0.01);病例主要集中在40~55岁人群,占48.76%;职业以农民为主,占89.26%。结论泗洪县流行性出血热疫情形势不容乐观,发病存在地区和人群差异,应切实加强重点地区灭鼠、重点人群预防接种工作,有针对性地开展健康教育。
