１９９６年对伊盟地区进行了健康人群的麻疹及白喉抗体水平的调查。调查结果显示，伊盟地区人群中麻疹抗体阳性率达９８．５％，ＧＭＴ为１∶２６．７４，而２１岁以上人群ＧＭＴ较高达１∶３９．６８。白喉抗体阳性率为５０．９７％，ＧＭＴ为１∶４．２７（０．０１７ＩＵ）。０～５岁组抗体阳性率为８７％，ＧＭＴ为１∶１６．８４（０．０６６ＩＵ）明显高于其它组，而２１岁以上人群抗体水平最低，阳性率１７．２４％，ＧＭＴ１∶１．４８（０．００５８ＩＵ）。大年龄组麻疹抗体较高可能与前几年这个地区麻疹流行有关。而白喉抗体在大年龄组较低也与该地区自１９９２年以来未有白喉流行有关
In 1996, the survey of measles and diphtheria antibody levels in healthy people in the Eritrea region was conducted. The survey results showed that the prevalence of measles antibody in the population of the Iran-EU region reached 98.5% with a GMT of 1:26.74, while the GMT of people above 21 years of age was as high as 1:39.68. Diphtheria antibody positive rate was 50.97%, GMT was 1: 4.27 (0.017IU). The positive rate of antibody in 0-5 years old group was 87%, GMT 1:16.84 (0.066IU) was significantly higher than that in other groups, while the antibody level was lowest in 21 years old and above, the positive rate was 17.24%, GMT1:1. 48 (0.0058IU). The higher age group measles antibody may be related to the prevalence of measles in this area a few years ago. While diphtheria antibodies were lower in older age groups and were also associated with the absence of diphtheria in the area since 1992
