This book is the work of 34 authors. They have approached the various diseases caused by viruses from the standpoints of history, characteristics of the virus, and the clinical findings caused by each virus. Chapters concerning physical properties of viruses, differentation between viruses, and infectivity characteristics, should be of interest to the microbiologist. They are highly technical. From the standpoint of the pediatrician, the chapters dealing with viruses as the cause of myocarditis, enteritis, dermatitis, respiratory tract infections, and central nervous system disease are of practical importance. The role of Coxsackie and ECHO viruses is stressed. Prophylaxis against influenza is discussed, and a routine for immunization of young children is recommended. Cultural and serological experiments on measles and varicella viruses are outlined. Because of its comprehensive coverage of the subject matter, this book should be excellent for reference use.
