摘要
于1987年4月～1987年9月在安徽省颍上县HFRS混合型疫源地对3个不同发病率地区春、秋峰前室内外的鼠密度及鼠带毒率进行了调查。结果发现:春、秋流行峰前发病率高、中地区的室内外鼠密度差异不显著,发病率低地区的野外鼠密度大于室内;3个地区春、秋流行峰前的鼠带毒率,鼠密度与鼠带毒率之积差异不显著,提示家鼠与野鼠共同担负了本病的宿主作用;通过对城乡春、秋流行峰前室内鼠密度、鼠带毒率的比较(差异无显著性),对家鼠在混合型疫源地中传播HFRS的作用进行了分析。
From Apr. to Sept. in 1987, a survey on the density of rodents, HFRS virus carrier rate indoor & outdoor before 2 epidemic peaks in localities with various degree prevalence in HFRS mixed epidemic area were conducted in Ying Shang county, Anhui Province. The result were:
1 No significant differehce on rodents' density between indoor&outdoor before 2 epidemic peaks in highly& intermiate epidemic focus but the density of mice in the field was higher than it indoor in HFRS lower epidemic focus.
2 No difference On HFRS virus carrier rate, rodents' density multiplied by its virus carrier rate between indoor & outdoor in all 3 localities before 2 epidemic peaks. It suggested that urban rats & wild mice coincided with human HFRS infection in the epidemic focus.
3 Rats as HFRS reservoir's role in mixed epidemic focus was quantitative analyzed by comparing density of rats & virus carrier rate between town & countryside.
