1987年4月至1988年3月,于HFRS春峰与秋峰之前,在安徽颍上发病率不同的三个农村点及一个城镇点,在病家与非病家的不同生境中,开展了鼠密度调查。结果表明:1.室内优势种为褐家鼠,占66.48%;其次是小家鼠,占33.52%。2.室内鼠密度以卧室及厨房为高,提示这些地方可能为HFRS在室内感染的主要场所;3.鼠在HFRS春、秋两个流行峰前的室内分布呈聚集性,带病毒鼠在室内的分布亦呈聚集性,这与人群发病局限性的特点相一致。
From April 1987 to March 1988, three rural sites and one urban site with different morbidity rates at Yingshang, Anhui before the HFRS Chunfeng and Qiufeng were carried out in different habitats of sick and non-sick Rat density survey. The results showed that: 1. The indoor dominant species was Rattus norvegicus, accounting for 66.48%; followed by Mus musculus, accounting for 33.52%. Indoor rat density in bedroom and kitchen is high, suggesting that these places may be the main site of HFRS infection in the laboratory; 3 rats in spring and autumn HFRS two epidemic peak indoor distribution was clustered, with the virus in rats indoors The distribution is also aggregated, which is consistent with the characteristics of the limitations of the population.
