This book presents the epidemiology of birth defects and their public health and social implications in India. As neglected childhood disorders, birth defects remain invisible in global maternal and child health dialogues. Birth defects services are emerging in India. This book approaches birth defects from a public health perspective, identifying the core functions of a birth defects service. Keeping in mind the complex task of providing multidisciplinary services for children with disabilities and complex medical conditions, the book examines the basic public health activities that have been put in place to address these conditions in India. The book describes birth defects surveillance and the challenges of acquiring accurate and timely data on birth defects against the background of India s mixed health system. It discusses opportunities for prevention of birth defects and describes the structure and function of an emergent genetic service.
