1998年洪灾之后，对灾区320名2～29岁健康人群进行了麻疹抗体水平监测，抗体阳性率为84.69％，几何平均滴度倒数（GMRT）为1585。以这次监测的抗体水平，灾区不会出现大面积的麻疹流行，但对局部大年龄组人群麻疹暴发或散发病例的出现应予以警惕。本次监测结果显示，25～29岁年龄组的阳性率只有75．00％，特别是汉川只有62.50％，应加强麻疹监测工作，针对不同情况采取相应的免疫策略。
After the 1998 floods, measles antibody levels were monitored in 320 healthy people aged 2-29 years with the antibody positive rate of 84.69% and the geometric mean titer reciprocal (GMRT) of 1585. With the antibody level monitored this time, a large area of measles epidemic will not occur in the affected areas. However, vigilance should be observed in cases of measles outbreaks or sporadic cases in the local large age group. The monitoring results show that the positive rate of 25 to 29 age group only 75.00%, especially only 62.50% of Hanchuan, measles monitoring should be strengthened to take appropriate measures for different situations.
