Time and space distribution characteristics in Anhui province between 2006 and 2010

目的:分析2006～2010年安徽省疟疾流行的时空分布。方法:收集全国2006～2010年疟疾发病数据,对我国疟疾流行情况进行统计分析,并绘制全国疟疾发病地理分布图。对安徽省疟疾流行情况进行年发病和季节发病的统计分析。结果:2006～2010年安徽省疟疾累计发病83 553例,居全国首位,年均发病率27.32/10万。发病率从每年的5月份开始上升,6～10月达高峰,10月后开始下降。2006～2010年疟疾发病数在安徽省甲、乙类法定报告传染病总数的排名除2010年为第16位外,其余均为前10位;在自然疫源性及虫媒传染病报告总数的排名一直位居第一位。结论:2006～2010年安徽省疟疾发病呈逐年下降趋势,但仍居全国一、二位。疟疾是安徽省发病率最高的虫媒传染病,仍需加强防治工作。
