1978～1998年佛山市登革热流行病学调查分析

根据佛山市法定传染病报告年报表 ,对佛山市 1 978～ 1 998年登革热的流行病学特征进行了分析。 2 1年间佛山市共发生五次有病毒学诊断依据的登革热大流行 ,共报告病例 2 541 8例 ,死亡 1 4例。疫情高度集中在顺德市、佛山市区 (城区和石湾区 )和南海市等旧疫区。 8～ 1 0月是流行的高峰季节 ,白纹伊蚊是佛山市登革热的传播媒介 ,人群普遍易感 ,旧疫区内健康人群血抑抗体水平较非疫区健康人群高 ,登革热旧患者血抑抗体水平逐年下降。今后预防工作的重点应在旧疫区。根据流行病学及病毒流行型别特点 ,登革热在佛山市可能已经形成地方性流行
