为了解陕西省麻疹流行病学特征 ,评价健康人群麻疹抗体水平 ,对麻疹发病和实验室资料进行分析。结果显示 :陕西省 2 0 0 3年麻疹流行模式为爆发和散发并存 ,局部地区麻疹爆发影响着全省麻疹发病水平 ,发病年龄和免疫史状况说明 8月龄～ 7岁为高发年龄段 ,该年龄段病例麻疹疫苗 (MV)接种率为 4 3%。 4、5月为麻疹高发月 ,病例数占全年病例总数的 6 0 %。麻疹抗体水平监测结果显示 :2 0 0 3年健康人群麻疹抗体阳性率和几何平均滴度倒数 (GMRT)较 2 0 0 1年上升明显 ,处于较高水平。 2～ 4岁麻疹抗体GMRT较低。提示MV初种和复种均必须加强 ,有效接种率有待提高。应对 1 5～ 2岁儿童增加 1次MV免疫 ,8月龄～ 14岁儿童开展MV的强化免疫。
In order to understand the epidemiological characteristics of measles in Shaanxi Province, the level of measles antibody in healthy population was evaluated and the incidence of measles and laboratory data were analyzed. The results showed that the epidemic pattern of measles coexisted in 2003 in Shaanxi Province. The occurrence of measles in some areas affected the incidence of measles in the whole province. The age of onset and history of immunization indicated that the age of 8 months to 7 years was the high incidence age. The measles vaccine (MV) vaccination rate was 43% in the age group. May and May were the high incidence of measles. The number of cases accounted for 60% of the total number of cases in the year. Measles antibody level monitoring results show that: in 2003 the healthy population measles antibody positive rate and geometric mean titer reciprocal (GMRT) increased significantly compared with 2001, at a high level. Measles antibodies 2 to 4 years old GMRT lower. Tips MV and seed multiplication must be strengthened, the effective vaccination rate needs to be improved. Should be 1 to 5 years old children increased 1 MV immunization, 8 months to 14 years of age children with MV boost.
