我国在流行性出血热(简称EHF)传染源调查方面做了大量工作,现经血清学证实31种小型动物携带EHF病毒(EHFV)抗原。我省证实有9种,其中啮齿动物占7种。本文试从鼠密度、带毒检测、病毒分离及结合流行病学特征,对我省所查出的带毒动物进行综合分析,为控制EHF的发生和流行提供预防对策。一、黑线姬鼠密度与EHF发病关系黑线姬鼠是我省EHF流行区野外主要优势种,在沿江疫区占鼠类构成比的94.2%,沿淮疫区占86.8%。根据其区系分布及季节消长与本病流行基本符合这一规律,通过1970~1974年的验证,证实用9月份黑线姬鼠密度预测本地区当年EHF疫情具有一定程度准确性(表1)。吴系科等[流行病学杂志1981;2(1):
A great deal of work has been done in the investigation of the source of epidemic hemorrhagic fever (EHF) in our country. Serotypes of 31 small animals are now confirmed to carry EHFV antigens. There are 9 species confirmed in our province, of which 7 species are rodents. In this paper, from the rat density, detection of poisoning, virus isolation and combination of epidemiological characteristics, we carried out a comprehensive analysis of poisoned animals detected in our province to provide preventive measures for the control of the occurrence and prevalence of EHF. The relationship between the density of Apodemus agrarius and the incidence of EHF The Apodemus agrarius is the main dominant species in the endemic area of EHF in our province, occupying 94.2% of the rodents in the epidemic area along the river and 86.8% in the coastal area along the Huai River. According to the laws of 1970s and 1970s, it was confirmed that the density of Apodemus agrarius in September was used to predict the epidemic situation of EHF in this area in the current year with a certain degree of accuracy (Table 1) .
