Viral zoonoses include a number of severe diseases that cause encephalitic or haemorrhagic manifestations in human beings. Arthropod vectors play important role in dissemination of many such infections. Rickettsiae, which phylogenetically occupy a position between bacteria and viruses, comprise another important group of zoonotic organisms. These are responsible for a diverse variety of vector-borne diseases. The present book " Zoonoses: Viral, Rickettsial and Prion Diseases" aims at developing an understandin of the animal-human-vector-microbe-environment interface and to conceptualize the strategies for prevention, control and elimination of major viral, rickettsial and prion diseases of zoonotic importance, with particular emphasis on the scenario in the developing countries. Simple language and apt illustrations make the contents of the book interesting and easily comprehensible. The book is an excellent learning resource for the students, teachers, researchers, academicians, planners and other professionals dealing with animal health, public health, wildlife management and environmental health. The professionals and organizations taking up health education programmes will also find it a great help.
