Sapovirus, a member of the family Caliciviridae, is one of the major causative agents of viral gastroenteritis affecting all age groups. A total of 3232 faecal specimens collected from infants and children with gastroenteritis in five different regions of Japan during 2003-2009 were examined for sapovirus by reverse transcription-polymerase chain reaction. Sapoviruses were detected in 131 (4·05%) patients with the peak observed mainly in the cold season (November-March) in Japan during 2003-2009. During the last 6 years, sapovirus GI/1 was the predominant strain in Japan followed by GIV, GII/3, GII/6, GII/2, GII/12 and GI, respectively.
肠道病毒，小核糖核酸病毒科的一个成员，是影响所有年龄段人群的病毒性肠胃炎的主要病原体之一。2003-2009 年期间，在日本五个不同地区收集了 3232 份患有肠胃炎的婴幼儿粪便标本，通过反转录-聚合酶链反应对肠道病毒进行了检测。在 131 例（4.05%）患者中检测到肠道病毒，主要发生在日本的寒冷季节（11 月至 3 月）。在过去的 6 年中，肠道病毒 GI/1 是日本的主要流行株，其次是 GIV、GII/3、GII/6、GII/2、GII/12 和 GI。
