Abstract

Between 1991 and 1994, serotypes and electropherotypes were determined for clinical specimens of group A human rotavirus (HRV) rotavirus collected from five different locations in the Asia, Saitama, Shizuoka, Taichung, Hong Kong, and Beijing. HRVs were detected through the year in Taichung and Hong Kong. The peaks of each rotavirus season were in January in Hong Kong, in March in Taichung, and in February and March in Saitama and Shizouka. We set one study year as that from July to next June.<BR>Serotype G1 was the most prevalent strain in the five different settings. Most of serotype G3 strains were identified in the study year 1991. Serotype G2 was the most predominant in Shizuoka and Taichung in the year 1993. Electropherotypes indicated the possible G types except in six cases of an unusual variant type whereas the serotype was G2 and the electropherotype was the “long” type. Five of the 502 cases and three of the 622 cases were identified as group C HRV by PAGE in Saitama and Shizouka respectively. In 216 samples in Taichung, no group C HRV strain was detected.
