Health is the ability of a biological system to acquire, convert, allocate, distribute, and utilize energy with maximum efficiency. It is not only the absence of disease but also the ability to realize one’s potential. It is a yardstick of ones well-being. Health status of a country can be assessed through indicators such as infant mortality rate, maternal mortality rate, life expectancy and nutritional levels, along with the incidence of communicable and non- communicable diseases.
