The present report is an overview of the research we have conducted. Amongst our research, we have demonstrated that the genetic evolution of the respiratory syncytial virus (RSV) undergoes both geographical and temporal clustering. Additionally, we have shown that the cytomegalovirus (CMV), a DNA virus, is widely disseminated under very stable genetic conditions. We have also clarified the situation concerning the genetic evolution of rotaviruses collected in Sapporo. In addition, we have attempted to identify the virulence-associated genome mutations of murine and human rotaviruses. Furthermore, we have indicated how the considerable genetic mutations of human parvovirus B19 could be associated with outbreaks of exanthema infectiosum every few years. Finally, we have examined viral reactivation in patients who underwent allogeneic hematopoietic stem cell transplantation and identified human herpesvirus 6 as a prominent pathogen causing important clinical events in these patients.}, pages = {1--8}, title = {ウイルスとこども達}, volume = {86}, year = {2017} }
