Emergent disease episodes have increased globally and served as reminder of the existence of infectious diseases. They have been an important part of human life due to their influence on human biology, sociology and even determine the course of major historical events. With the world becoming a smaller place to live in, exotic pets and wild animals becoming more accessible, the risk of human being exposed to additional diseases is possible. Furthermore, there have been threats of new diseases during the past two decades due to the evolution and adaptation of microbes and the re-emergence of old diseases due to the development of antimicrobial resistance and their capacity to spread to new geographic areas. Considering the fact that most of the emerging diseases are often zoonotic in nature, the significance of zoonoses in the emergence of human infections cannot be overstated. Around 61% human microbial pathogens and 73 % emerging human pathogens identified during the past two decades are zoonotic (Gregar, 2007). Approximately 75 % of disease that have emerged over the past two decades may have a wildlife source (Woolhouse, 2002). Morens et al, 2004, reported that fight against zoonoses starts by eliminating the pathogen at its animal source. So the need to understand disease of animals has become more apparent and which give both opportunity and challenge for the veterinarians as they have both clinical and population medicine training as well as education in disease control. This review of emerging and re-emerging diseases should be of critical importance to microbiologists, clinicians, public health personnel and policy makers in India.
