目的 分析闵行区2006-2010年疟疾疫情流行特征,为科学防治疟疾和消除疟疾目标提供依据.方法 收集2006-2010年疟疾监测数据、疫情流行病学调查资料和全国疟疾监测点数据进行统计分析.结果 5年间闵行区共发生疟疾115例,平均发病率为0.62/10万,未出现疫情暴发和危重、死亡病例.各年发病率总体呈下降趋势,分别为1.66/10万、1.92/10万、1.54/10万、0.75/10万和0.32/10万.输入性病例是本地病例的9.45倍(104/11),输入性病例以安徽籍病例为主,占81.73%(85/115);疟疾复发病例占15.65%(18/115);病原学分型以间日疟为主,占80.87%(93/115),4例恶性疟均由境外感染引起;年龄分布以20～45岁青壮年为主,占57.39%;职业分布以民工和学生为主,分别占40.00%和20.00%;全区以及全国疟疾监测点"三热"病人疟原虫血检阳性数和阳性率均呈逐年下降趋势;疟疾监测点媒介监测显示:传疟媒介按蚊仍然存在,但密度不高.结论 闵行区疟疾疫情已控制在较低水平,且总体呈下降趋势,近2年下降尤为明显,为2015年达到消除疟疾的目标和计划奠定了基础.但本地感染病例和传疟按蚊仍然存在,因此疟疾防制不可放松,应重点加强外省尤其是安徽籍和境外输入性疟疾病例的防制.
