This book is aimed to emphasize the rationale and importance of prevention and management of viral hepatitis in children, providing cutting edge knowledge. Viral hepatitis is a major health problem in the world. Although most complications of viral hepatitis are observed in adults, primary infection with hepatitis viruses often occurs during infancy or childhood. To better control viral hepatitis, prevention and therapy if possible should be started in childhood. This book offers updated and unique information about viral hepatitis in children, which has vitally important impact on global disease outcome and control, yet not discussed as frequently as viral hepatitis in adults in previous medical literature. Better prevention and management strategies are covered, starting from infancy and childhood, and even earlier during fetal life. It will be very helpful for better control of viral hepatitis both for daily practice and for developing future strategies and directions. If we can successfully control viral hepatitis in children, there will be very little remaining chronic hepatitis and related complications such as liver cirrhosis or hepatoma in adults. We hope readers, including medical students, researchers, pediatricians, family medicine physicians, infectious disease personnel, public health workers, gastroenterologists, hepatologists and parents of children with chronic hepatitis, will be benefited by reading this book.
