目的对新疆麻疹疑似病例进行鉴别诊断,正确掌握强化免疫后麻疹疫情动态。方法2004年11月对全疆学龄前和学龄儿童进行麻疹疫苗强化免疫,2005年对收到的237例麻疹疑似病例血清标本测定了麻疹IgM抗体和风疹IgM抗体。结果麻疹IgM抗体阳性率3.38%,风疹IgM抗体阳性率67.62%,8个月~14岁年龄组184例,风疹阳性率最高(64.67%)。结论有部分风疹病例误诊为麻疹,提示我们在麻疹消除阶段应密切注意风疹的流行和监测。
Objective To identify the suspected cases of measles in Xinjiang and to correctly understand the epidemic situation of measles after the intensive immunization. Methods The measles vaccine was boosted in preschool and school-age children in Xinjiang in November 2004. Measles IgM and rubella IgM antibodies were detected in serum samples from 237 suspected cases of measles in 2005. Results The positive rate of measles IgM antibody was 3.38%, the positive rate of rubella IgM antibody was 67.62%, and the incidence rate of rubella was 84.67% in 184 cases of 8 months to 14 years old group. Conclusion Some rubella cases were misdiagnosed as measles, suggesting that we should pay close attention to the epidemic and monitoring of rubella during the period of eliminating measles.
