[目的]探讨麻疹流行的季节性规律,为制定麻疹防治策略提供依据。[方法]应用集中度及圆形分布法,对南昌市1985～2007年的麻疹季节性分布进行分析。[结果]南昌市1985～2007年的麻疹季节性分布的M值为0.5326,r值为0.5326。[结论]麻疹发病有季节性分布特征,疫苗干预可使麻疹发病高峰日后移,但不会改变麻疹发病的季节性流行规律。
[Objective] The study aimed to discuss the seasonal regularity of measles epidemic and provide the basis for formulating measles prevention and control strategies. [Method] The concentration distribution and circular distribution method were used to analyze the seasonal distribution of measles in Nanchang from 1985 to 2007. [Result] The M value of seasonal distribution of measles in Nanchang from 1985 to 2007 was 0.5326, and the r value was 0.5326. [Conclusion] The incidence of measles is seasonal distribution.
