Health is one of the vital indicators reflecting the quality of life and therefore it has been rightly said, 'Health is wealth'. Though preservation and promotion of health is one of the most basic human rights, India is stilllaggingbehind in realising this aspiration. Public health is concerned with the health of the community as a whole. Its key goal is to reduce population's exposure to disease. It has been said that: "Health care is vital to all of us some of the time, but public health is vital to all of us all of the time".
