摘要
目的 探讨绍兴市麻疹发病的季节性及其变动趋势。方法 采用集中度和圆形分布法对该市1955-1964年、1965-1983年、1984-2001年3个阶段的麻疹发病资料进行时间聚集性分析。结果 两种分析方法获一致的统计分析结果,即麻疹发病具有一定的季节性。用圆形分布法求得3个阶段发病高峰时点分别为3月12日、3月24日及4月25日,高峰时期分别为12月29日~5月23日(148天)、1月7日~6月12日(155天)和2月27日~6月26日(120天)。3个阶段高峰时点经Watson与Williams检验差异有显著性。结论 绍兴市麻疹发病高峰时点后移,自1965年使用麻疹疫苗后,高峰时期缩短,发病季节性增强。
OBJECTIVE To study the incidental seasons and variable tendency of measles in Shaoxing.
