为了解江西省风疹流行情况 ,对 9个地区出疹性病例进行了调查 ,并随机采集急性期血清 2 31份进行风疹和麻疹IgM抗体检测。结果表明 :2 31份血清中 ,麻疹IgM抗体阳性 39份 ,分属 10次流行 ;131份血清中 ,风疹IgM抗体阳性 92份 ,分属 13次流行。采血时间与风疹IgM抗体检出率密切相关 ,以出疹后 5～ 14天检出率最高 (85 71% )。流行人群中以学龄儿童为主 ,其中 11～ 15岁风疹IgM抗体阳性率最高 (81 40 % ) ,其次为 7～ 10岁 (6 4 79% )。所有血清标本均以疑似麻疹病例报告送检 ,均无风疹疫苗免疫史 ;其中从两个县的送检血清标本中还发现风疹和麻疹同时在不同乡、镇中流行的现象。以上结果提示 :江西省风疹流行情况有时严重 ,人群抗体水平低 ,且与麻疹混淆 ,误诊情况普遍。因此 ,加强风疹疫苗接种和风疹IgM抗体检测工作刻不容缓
In order to understand the epidemic situation of rubella in Jiangxi Province, the cases of measles in 9 regions were investigated, and 231 cases of acute phase serum were collected for IgM antibody detection of rubella and measles. The results showed that among 231 serums, 39 were positive for measles IgM antibody, which belonged to 10 epidemics. Of the 131 serum samples, 92 were positive for rubella IgM antibody, belonging to 13 epidemics. Blood sampling time and rubella IgM antibody detection rate is closely related to the detection rate of 5 to 14 days after the rash (85 71%). Among the epidemic population, the majority of school-age children, the highest positive rate of rubella IgM antibody was 11-40 years old (81 40%), followed by 7 to 10 years old (64 79%). All the serum samples were reported in suspected measles cases. There was no history of rubella vaccine immunization. Among the serum samples from two counties, rubella and measles were also found in different towns and villages at the same time. The above results suggest that the epidemic situation of rubella in Jiangxi Province is sometimes serious, the level of antibody in the population is low, and it is confused with measles and misdiagnosis is common. Therefore, to strengthen the rubella vaccination and rubella IgM antibody testing without delay
