Public health is a vivacious part of any healthcare system of a country and is accountable for plummeting health risks and eventually sustaining and improving health status.

Public health professionals play a crucial role in maintaining a healthy community. A public health professional is a person educated in public health or a related discipline who is employed to improve health through a population focus. Public health is a fusion of many decussating disciplines, including but not limited to: medicine, behavioural and social sciences, statistics, management, administration, communication, environment, nutrition, epidemiology, law, public policy and ethics. A developing and emerging country like India provides the best platform for the career development in public health sector.

They are very important for improving access and quality health care for the population. They create awareness and counsel patients to deal with their physical and mental issues.

These include child malnutrition and low birth weights that often lead to premature death or lifelong health problems; high rates of neonatal and maternal mortality; growth in non-communicable diseases such as obesity, diabetes, and tobacco and alcohol abuse, leading to cancer and other fatal diseases. As the Indian government struggles to provide health coverage broadly, the country’s healthcare system always remains an area of concern especially in rural areas. There are differences in health care systems in rural and urban areas. Furthermore, increasing lifestyle ailments like heart diseases, cancers or diabetes is also reported in recent years. This is happening because of an implementation of unhealthy western lifestyle involving diet high in fat and sugar content. Lifestyle diseases claimed more than 52 lakh lives in the year 2008. Heart related diseases have the highest segment. Diabetes also becomes the most alarming health issue with regard to public health in India. While there were only 2.1% diabetics in urban India in the 1970s, the number has grown to 12.1% for adults above the age of 20. Latest study by International Diabetes Federation suggests that there were 36.6 crore diabetics all over the world in 2011, out of which 6.1 crore were from India, justifying the nation to be the diabetes capital of the world.
