Recently, rapid developments have occurred in the field of viral gastroenteritis. This book is an update of fundamental and practical aspects of viral gastroenteritis. Among the various agents that cause viral gastroenteritis, group A rotaviruses and caliciviruses are the focus of this volume because of their clinical impact and the significance of new findings about them.
