The book ‘Medical and Veterinary Virology’, is an intelligent collation of concepts in viral diseases affecting humans and animals. The authors have taken an approach of dealing with viruses as causes of infectious syndromes, paying attention to fundamentals of virus pathogenesis, host response and virus detection in the laboratory in the early part of the book. All the important virus disease syndromes have been described lucidly with special chapters on the treatment and prevention of these diseases. This book should cater to the needs of undergraduate and post graduate students of medicine and veterinary sciences, post graduate science students particularly, microbiology and biotechnology students with special interest in virology as a part of their course. The book is structured in a manner that each chapter is comprehensive; this may, in some cases, produce minimal overlap of information. This is unavoidable in a textbook that takes a syndromic approach to viral causes of important infectious diseases.
