The HI assay for measles was used to evaluate the sera of 191 children of preschool age (1-6 ys) from five regions of South Yemen: highland, coastal, Vadi Hadramot, the agricultural area Abijan and the capital city Aden. The serum positivity rate was 47.5% in 1-2-year-old children, 75.5% in 3 year-old and 88.5% in 4-6 year-old children. The geometric mean of HI titres was 4.8 log2 in preschool children. An optimal strategy of vaccination against measles in Yemen is discussed.
采用麻疹血凝抑制试验(HI试验)对来自南也门五个地区的191名学龄前儿童(1 - 6岁)的血清进行评估,这五个地区分别是:高地、沿海地区、瓦迪哈德拉毛、农业区阿比扬以及首都亚丁。1 - 2岁儿童的血清阳性率为47.5%,3岁儿童为75.5%,4 - 6岁儿童为88.5%。学龄前儿童HI滴度的几何平均值为4.8 log2。文中还讨论了也门预防麻疹的最佳疫苗接种策略。
