| Abstract: |
| 1984年春末夏初,我们随机检测了新安县家鼠型疫区274名正常人的EHFV抗体,3月IgG检出率为11.3%,IgM为0;7月IgG检出率为16.4%,IgM为0.7%。其间GMT无明显变化,抗体阳转者未见EHF感染症状。同时同地对褐家鼠鼠群EHFV带病毒率、抗体阳性率、GMT及其分布变化的逐月监测表明,鼠群在此期间发生了EHFV感染和播散的自限性变化。鼠群EHFV感染的季节性突增,可能与其交配繁殖中广泛、密切的接触有关,这与当地人群EHF流行的季节性变化有一定关系。发现疫区附近家兔和猪的EHFV抗体阳性率分别为5.65%和6.13%,从2只家兔脾中检出了EHFV抗原。 |

| EHFV Antibodies were tested in a total of 274 randomly selected healthy individuals in Xinan county, 1984. The EHFV antibody prevalence rate was 11.3% in March and 16.4% in July. No symptoms could be found in those seroconverted cases. Meanwile, a dynamic change of EHFV infection was found among R. norvegicus population, according to the monthly data of EHFV carrying rates, EHFV antibody prevalence rate, GMT and changes in their composition fraction in the same area. The seasonal increase of EHFV infection among. R.norvegicus may be caused by the broad and close contact during theiractine mating and breeding in spring. This apparently provided the basis for the epidemic of the rat type EHF in humans. Some rabbits and Pigs arround Xin-an county were found to be infected by EHFV, and the antibody Prevalence rate was 5.65% and 6.13% respectively. EHFV antigen had been found in the spleen of two rabbits. |
