Epidemic patterns of 12 infectious diseases based on the data derived from the surveillance system of infectious diseases in Japan are analyzed. Weekly numbers of patients per one monitor station (general clinics and hospitals) are calculated by prefecture. Based on these data, the patterns of epidemic are classified into five categories: Category 1, nationwide outbreak of short duration (rotavirus enteritis, hand-foot-mouth disease and herpangina); Category 2, nationwide outbreak of long duration (varicella); Category 3, concurrent outbreaks in several districts (rubella and erythema infectiosum); Category 4, epidemic of long duration in several prefectures at different times (measles, mumps, pertussis, streptococcal infection and atypical pneumonia); Category 5, unclear epidemic pattern (exanthema subitum).
基于日本传染病监测系统的数据，对12种传染病的流行模式进行了分析。按县计算每个监测站（普通诊所和医院）每周的患者数量。基于这些数据，将流行模式分为五类：第1类，短时间内全国范围的爆发（轮状病毒肠炎、手足口病和疱疹性咽峡炎）；第2类，长时间全国范围的爆发（水痘）；第3类，几个地区同时爆发（风疹和传染性红斑）；第4类，不同时间在几个县长时间流行（麻疹、腮腺炎、百日咳、链球菌感染和非典型肺炎）；第5类，不明的流行模式（幼儿急疹）。
