The value of West Nile virus immunoglobulin G avidity for distinguishing recent from past infection was investigated using 348 follow-up specimens from 170 viremic blood donors. Low avidity accurately indicated infection within the previous 4 months. However, due to rapid avidity maturation in some individuals, high avidity did not accurately indicate past infection.
利用来自170名病毒血症献血者的348份随访样本,研究了西尼罗河病毒免疫球蛋白G亲和力在区分近期感染与既往感染方面的价值。低亲和力准确表明在过去4个月内感染。然而,由于一些个体中亲和力迅速成熟,高亲和力并不能准确表明既往感染。
