摘要: 目的探讨天台县肾综合征出血热(HFRS)的流行特征和发展趋势,以制定有针对性的防制措施。方法采用描述流行病学方法统计分析HFRS疫情资料,人间疫情流行病学调查,采用间接免疫荧光法检测病人及健康人血清抗体;宿主动物带病毒率调查,采用直接免疫荧光法检测鼠肺汉坦病毒(HV)抗原。结果2001~2003年全县累计报告HFRS病例165例,年平均发病率为9.94/10万。男女发病比例为3.23∶1(126/39),以农民发病为主,占81.82%。室内鼠密度平均为2.51%,野外为5.22%,总鼠密度为4.53%,鼠带病毒率平均为16.38%。病人血清阳性率81.37%。结论天台县是以姬鼠型为主的混合型HFRS疫区,需要进一步加大监测和预防力度。
