肾综合征出血热混合型疫区地理景观与宿主动物结构及疾病发生关系的研究

The Study on the Relationship Among Geographical Landscape,. Host Animal and Occurrence of Disease in HFRS Mixed Epidemic Focus

本文报道1983年4及9月份肾综合征出血热春、秋流行峰前在本省某县进行疫区内地理景观调查的结果。发现:小麦地、红薯地及花生地为利于鼠类活动的生态环境;地势低、土质疏松地区的鼠密度、鼠带毒率及人群感染水平,均高于地势高、土质硬的地区。

From April to September in 1988. a geographical inveatigation Was conducted before HFRS spring and Autumn epidemic peaks in a county in Anhui Frovince. We found that wheat peanut and sweet potato fields are convenient ecological enviroment for the resident of mice. We also found that the population incidence rate of HFRS, rodent's density and positive rate of HFRS virus antigens in shoaly land with lower terrain and silt loam were higher than those in hillock with higher terrain and sandy loam.
