[Incidence and prevalent types of Norwalk virus, Sapporo virus and human astrovirus in pediatric gastroenteritis in Hiroshima Prefecture].
The incidence and prevalent types of Norwalk virus (NV), Sapporo virus (SV), and human astrovirus (HAstV) in pediatric gastroenteritis in Hiroshima Prefecture were investigated in 7 cold seasons, between 1995/96 and 2001/02. The incidences of NV, SV, and HAstV were 23.6% ranging from 16.3 to 34.4, 2.5% ranging from 1.5 to 4.7, and 3.2% ranging from 1.5 to 6.0, respectively. The peak of the incidence of NV was found in November and December. No accumulation of monthly incidence in SV or HAstV was noted. Most NVs detected belonged to genogroup II. A probe type of G2F, according to Fukuda et al., was predominant in NV, followed by G2E and G2B. The probe types of LON and SAP, according to Vinje et al., were predominant in SV. Serotype 1 was predominant in HAstV.
