ABSTRACT
A total of 10,917 fecal specimens from infants and children with gastroenteritis in seven different regions of Japan in the last 3 decades were examined for rotavirus. We observed that the rotavirus peak shifted gradually from January to April (winter to early spring) during 17 seasons and the G1P[8] combination was the most predominant genotype in the last 28 years in Japan.

ABSTRACT
We investigated the incidence of sapovirus (SaV)-associated gastroenteritis in infants and children in Japan during 2007-2008 and characterized the diversity of SaV-positive strains. SaV was detected in 19 (4%) of 477 fecal specimens. The leading genogroup (79%, 15 cases) comprised intergenogroup recombinant SaVs (GII/GIV).
