用间接免疫荧光法对吉林省延边地区305例儿童外周血及40份脐带血进行了EB病毒抗体的检测,在0～2月组其阳性率为85.7％,此后阳性率下降,5～6月组为25.0％,达最低值,7～11个月组抗体阳性率为33.3％,1岁组为72.5％,1～3岁组阳性率急剧上升,以后保持在90～100％。汉族儿童的抗体阳性率高于朝族儿童,两者之间有显著性差异(P<0.05)。
The indirect immunofluorescence method was used to detect Epstein-Barr virus in 305 cases of peripheral blood and 40 cases of umbilical cord blood in Yanbian area of Jilin Province. The positive rate of EBV antibody was 85.7% in 0 ~ 2 months, and the positive rate decreased from May to June The positive rate was 33.3% in 7 ~ 11 months group and 72.5% in 1 year old group. The positive rate in 1 ~ 3 years old group increased sharply, and remained at 90 ~ 100% later. The positive rate of antibody in Han children was higher than that in the children of the North Korea nationality (P <0.05).
