河北省肾综合征出血热国家级监测点宿主动物监测分析

目的了解河北省肾综合征出血热（HFRS）国家级监测点宿主动物的构成、分布及携带汉坦病毒状况,为HFRS的防制提供科学依据。方法在全省4个国家级监测点,分别于春季、秋季开展宿主动物调查,采用夹夜法调查鼠密度,免疫荧光法检测鼠肺病毒抗原。结果 2005-2009年监测点居民区鼠密度波动在0.63%～2.50%之间,野外鼠密度波动在0.37%～0.71%之间,居民区鼠密度高于野外（χ2=177.05,P〈0.01）;鼠带病毒率居民区为1.76%,野外为0.84%;鼠种构成以褐家鼠为优势鼠种（77.39%）,其次为大仓鼠（12.42%）和小家鼠（8.70%）;12份阳性鼠肺中,褐家鼠占83.33%（10/12）,小家鼠和大仓鼠各占8.33%（1/12）。结论褐家鼠是河北省HFRS的主要宿主动物和传染源,在HFRS的传播中起到重要作用;鼠密度和鼠带病毒率均较低,预示河北省HFRS不会出现大的流行。

Analysis of the surveillance data on host animals in the national monitoring sites of hemorrhagic fever with renal syndrome in Hebei province

Objective To get an insight into the composition, distribution and HV-carrying condition of host animals in the national monitoring sites of hemorrhagic fever with renal syndrome (HFRS) in Hebei province, providing scientific evidence for the prevention and control of the epidemic. Methods Investigations of host animals were carried out in spring and autumn, respectively, in the four national monitoring sites, with the trap-night method used for the detection of the density of rats and immunofluorescence te...
