【摘要】 佳木斯市1974～1985年EHF流行的规律是,继第一次流行高峰年之后,间隔5yr进入本次流行高峰阶段,并呈现发病率明显增高的趋势;流行季节是10～12月,出现明显的秋峰,该现象与鼠密度相关;本地优势鼠种与文献报道一致,但室内、外EHF的储存宿主有交叉重叠现象,是疫区长期存在并不断扩大的主要原因;通过EHF患者血清抗体测定,发现病后,血清抗体滴度随病程延长而增长,发病4wk以后检测血清抗体,阳性率可达100%。更多还原

【Abstract】 In Jiamusi from 1974 to 1985 FHF is characteristic of occurrence of another peak 5 years following the first epidemic peak. There is a tendence to increase in the incidence. The epidemic season is from October to December, showing a obvious autumn summit, which is associated with the density of mouse. Serum antibodies were determined in EHF patients and it was found that serum antibody titre was increased 4 weeks after attack.With a prolonged duration of the disease the positive rate reached 100% when serum antibodies were determined 4 weeks after attack.更多还原
