| Abstract: |
本病主要宿主动物,疫源地类型及流行程度,随着不同地形地貌而异。福建19℃等温线以北的Ⅰ、Ⅱ地理区划,有黑线姬鼠分布,存在家野鼠混合疫源地;该线以南Ⅲ、Ⅳ地理区划,无黑线姬鼠分布,仅有家鼠型疫源地。家野鼠混合疫源地比仅家鼠型疫源地的流行程度强。黑线姬鼠构成比和带毒率越高的地区流行越强。健康人群隐性感染率家鼠型地区比野鼠型地区高。
本病流行因素除与地形地貌,主要宿主动物种类及带毒鼠EHF抗原携带率有关外,尚应考虑病毒毒力和带毒鼠种的密度。 |

| The data showed that the main host animal, type of nature foci and prevalence intensity were varied with the geographic divisions. there were mixture natural infectious foci of Rattus and Apodemus in the Ⅰ and Ⅱ geographical divisions e.g. north of 19℃ isotherm where the Apodemus agrarius existed, while there was natural in fectious focus of Rattus norvegicus only in the Ⅲ and Ⅳ geographical division e.g. south of 19℃ isotherm where the A. agrarius was not existed. The high density and high rate of virus carriers, of A. agrarius the more prevalence intensity. Besides geographic prospects, kinds of main host animals and rate of EHF virus carrier, prevalence of EHF was related to virulence of the virus and density of the rat carrying the virus. |
