I am Bandana Dobhal. I am a graduate in Prosthetics and Orthotics from 'Pt. Deendayal Upadhyaya National Institute for Persons with Physical Disabilities', New Delhi. Currently pursuing Master of Public Health from Amity University, Noida. Having this background, motivated me to write this book, as it focuses on improving and protecting community health and well-being, with an emphasis on prevention among the population.
