| Abstract: |
| 1981年10月~1984年1月在河南省新安县两个观察点进行流行性出血热传染源的调查,发现褐家鼠是村内优势鼠种(57.9~81.4%),其携带EHF病毒抗原者占8.76%,为全部带毒鼠的87%。野外优势鼠种(54.3%)的黑线姬鼠,检奄359只,均未发现带毒鼠。褐家鼠带毒的季节高峰与人群发病率高峰有密切关系。说明褐家鼠是当地流行性出血热的主要传染源。未发现当地黑线姬鼠参与本病传播的证据。 |

| Survey on the role of Rattus norvegicus was carried out in two survey spots in Xinan County of Henan Province from October, 1981, to January, 1984. it was found that R. norvegicus was the predominant species of house rodents in the studied are as (57.9-81.4%), and the highest virus carrying rate was demonstrated among this rodent (87.0% of all EHF virus carrier rodents). No positive result could be found among 359 Apodemus agrarius,the predominant species of field rodents in the studied areas (62.7). The seasonal fluctuation of EHF virus carrying rate in R. norvegicus apparently paralleled with that of the incidence of human EHF. It was thus concluded that the chief source of infection for humans was R. norvegicus and Apodemus mice apparently was not evidenced to implicate in the transmission of EHF virus in the case. |
