摘　　要：[目的]了解1996—2008年上海市浦东新区麻疹发病情况,分析麻疹发病的季节性规律并探讨麻疹发病率升高对其发病季节性的影响。[方法]采用圆形分布法,比较和分析发病率不同水平时期的麻疹发病高峰日和高峰期的情况。[结果]6个时期麻疹发病的高峰日分别为4月18日、5月11日、9月18日、5月17日、4月9日和5月19日;高峰期分别为120、129、194、136、100、163 d;1996—2008年,发病高峰更趋规律,以4—5月为主;高峰期可受最高月病例构成的影响,发生相应的改变。[结论]麻疹发病率升高,不能改变麻疹的季节性和发病高峰;圆形分布法分析单峰型有季节特征的麻疹的发病高峰特征,简明扼要,描述直观。[Objective] To investigate the seasonal prevalence of measles from 1996 to 2008 in Pudong New Area of Shanghai. [Methods] Circular distribution method was used to compare and analyze the situations on the peak day and in the peak duration of measles morbidity at periods of different morbidity levels. [Results] The peak days of the 6 prevalence periods were April 18,May 11,September 18,May 17,April 9 and May 19,with the peak duration being 120 days,129 days,194 days,136 days,100 days and 163 days,respectively.The peaks of measles prevalence concentrated in April and May. [Conclusion] Rise of measles morbidity cannot change its seasonal prevalence or peak time.Simple calculation and intuitive description have advantages of circular distribution method in analyzing the seasonal variation of diseases with single peak and cyclic change.
