[目的]了解麻疹疑似病例血清麻疹IgM抗体水平,为今后控制和消除麻疹采取措施提供科学依据。[方法]对2008年聊城市各县(市、区)送检的678份麻疹疑似病例血清麻疹IgM抗体检测资料进行分析。[结果]检测血清678份,麻疹IgM抗体阳性的438份,阳性率为64.60%。抗体阳性率,4~11月龄为81.73%,1~4岁为49.50%,5~14岁为51.25%,≥15岁为68.16%(P<0.01);1~3月为67.20%,4~6月为65.87%,7~9月为58.33%,10~12月为58.82%(P<0.01);采血时间在发热第0~3 d的为41.94%,4~7 d为69.66%,8~14 d为67.96%,≥15 d为50.33%(P<0.01)。[结论]聊城市麻疹疑似病人麻疹IgM抗体阳性率较低。
[Objective] To understand the serum measles IgM antibody level in suspected cases of measles and provide a scientific basis for future measures to control and eliminate measles. [Method] The detection data of 678 serum measles IgM antibodies in suspected cases of measles sent in all counties (cities and districts) of Liaocheng in 2008 were analyzed. [Results] The positive rate of 678 serum samples was 438 with the positive rate of 64.60%. The antibody positive rate was 81.73% in 4-11 months, 49.50% in 1-4 years, 51.25% in 5-14 years and 68.16% in 15 years old (P <0.01), 67.20% in 1 ~ 65.87% in June-June, 58.33% in July-September and 58.82% in 10-12 (P <0.01). The blood sampling time was 41.94% on day 0 to 3 of fever and 69.66% on day 4 to 7, 8 ~ 14 d was 67.96%, ≥ 15 d was 50.33% (P <0.01). [Conclusion] The positive rate of measles IgM antibody in suspected measles patients in Liaocheng City is low.
