目的为传染病季节分布的研究提供科学的统计学方法。方法运用集中度法及圆形分布法对闽侯县2001～2008年6种常见传染病的季节分布特征进行分析。结果麻疹有一定季节性;而痢疾、伤寒、甲肝、肺结核、乙肝为全年散在发病。结论圆形分布法可计算出疾病的发病高峰时点和高峰期。而集中度却不能;集中度能较真实地反映疾病发病的季节性分布。
Objective To provide a scientific statistical method for the study of seasonal distribution of infectious diseases.

The results of measles have a certain seasonal; and dysentery, typhoid fever, hepatitis A, tuberculosis, hepatitis B scattered throughout the year.
