Nearly 1000 sera from children were tested by immunoelectro-osmophoresis against BK virus, and age-specific prevalence rates were estimated from birth until the age of 12 years. Declining rates during the first 12 months showed the waning of passive immunity, which at birth reflects the mother's immune status. The changes of prevalence suggested that the peak incidence of primary infections occurred at about 2 years, with an estimated peak annual rate of 24.6%.
通过免疫电渗电泳法对近1000份儿童血清进行了检测，以检测是否感染BK病毒，并估算了从出生到12岁各年龄段的感染率。出生后前12个月感染率下降表明被动免疫减弱，出生时的被动免疫反映了母亲的免疫状态。感染率的变化表明，初次感染的高峰发病率约在2岁时出现，估计年发病率峰值为24.6%。
