遂平县鼠类生态与流行性出血热发病关系的研究

1984年4月至1985年3月,在遂平县定时、定点对鼠类生态与出血热发病进行调查的结果证明:黑线姬鼠是本区野外的优势种,也是出血热的主要染源。虽然纹背仓鼠的密度低于前者,但带毒率更高,故应给予应有的重视。鼠类密度在4月及9月各形成一个高峰。其密度,带毒率和发病人数的消长曲线基本一致,紧密相随。故灭鼠是控制该病的关键。作者认为:每年2～3月及7～8月各进行一次室内外灭鼠,对防病保粮有更好的效果。

A STUDY OF THE RELATIONSHIP BETWEEN RODENTS ECOLOGY AND THE INCIDENCE OF EHF

From,April 1984 to March 1985,an investigation of the rela—tionship between rodents ecology and the incidence EHF was madeat regular intervals and in fixed townships in Suiping County.Theresult of the investigation indicates that Apodumus agrarius wasthe dominant species in the fields and the main source of thedisease.Although the density of Cricetulus barabensis was lowethan that of Apodumus agrarius its percentage of virosis—carrierswas higher,so that sufficient attention must be paid to the species.There were two peaks of density flactuation in April andSeptember respectively.The three flactuation curves,i.e.the flac—tuation curve of density.,flactuation curve of the percentage ofvirosis—carriers and flactuation curve of the number of people whocaught the disease,were roughly in agreement and followed clos—ely one after another.This manifests that the key to controllingthe disease is the killing of the rodents.We hold that we sh—ould unfold two major movements of killing rodents:one within Feb—rouary and March just before their breeding and the other withinJuly and August before the peak of the virosis—carrying period.By so doing,we can prevent the disease effectively and do a bet—ter job of grain preservation
