Outline of Final Research Achievements

It has been suggested that replication of rotavirus in intestinal tissue is not important for pathogenesis of severe complications such as encephalitis and sudden unexpected death. Additionally, no remarkable findings suggesting direct invasion of virus into central nervous system were demonstrated in this study. Thus, present data suggests that host immune response may play important role in pathogenesis of these severe complications. Incidence of these severe complications in Japan were estimated based on the epidemiological analysis carried out in Aichi prefecture. After starting support of vaccination cost from the local governments, number of the cases with severe rotavirus associated complications appears to be declined. Further follow up study is necessary to confirm this finding.
