目的了解喀什地区健康人群脊髓灰质炎(以下简称脊灰)、麻疹、甲肝、乙肝免疫水平,评价预防接种效果。方法按容量比例概率抽样方法抽取乡、村,每个村抽取10人(各年龄组),采用酶联免疫吸附试验(ELISA)法检测<1岁、1~2岁、3~4岁、5~6岁、7~14岁、15~19岁、20~岁组7个年龄组人群脊灰、麻疹、甲肝、乙肝IgG抗体。结果健康人群中脊灰、麻疹、甲肝、乙肝IgG抗体总阳性率分别为68.68%、62.42%、83.35%、53.02%。四者中甲肝IgG抗体阳性率最高,乙肝IgG抗体阳性率最低。结论喀什地区健康人群的脊灰、麻疹、甲肝、乙肝IgG抗体阳性率较低,不能形成牢固的群体免疫屏障,建议通过改变服务模式、规范技术操作等提高接种质量。
Objective To understand the polio (polio), measles, hepatitis A and hepatitis B immunization in healthy population in Kashgar region and evaluate the effect of vaccination. Methods Totally 10 people (each age group) were drawn in each village according to the sampling method of capacity proportion probability. The serum samples were collected at the age of 1 year, 1 to 2 years, 3 to 4 years, 5 ~ 6 years old, 7 ~ 14 years old, 15 ~ 19 years old, 20 ~ age group 7 age groups polio, measles, hepatitis A, hepatitis B IgG antibodies. Results The positive rates of polio, measles, hepatitis A and hepatitis B IgG in healthy population were 68.68%, 62.42%, 83.35% and 53.02%, respectively. Hepatitis A IgG antibodies in the four positive rate of the highest, the lowest positive rate of hepatitis B IgG antibody. Conclusion The positive rates of poliovirus, measles, hepatitis A and hepatitis B IgG antibodies in healthy population in Kashgar region are low, which can not form a strong population immune barrier. It is suggested that vaccination quality can be improved by changing service mode and regulating technical operation.
