Good health is vital for human life and the development of society. This interlinkage was explained by Michael Grossman (1972) in a model, which shows that an individual consumes healthcare to improve their stock of health, which, in turn, is translated into a productive resource. A World Bank report (1993), Investing in Health, considered public health as a public good and warned against the deleterious effect of poor health on individuals and households; it also stated that better health translates to economic progress at a national level.
The World Health Organization (WHO) has also established the causality between health and economic development, which was observed by Amrtya Sen (2002) as the core element of social justice. The United Nations (UN) prioritised health in its ambitious international agenda of Millennium Development Goals (2000-2015) and Sustainable Development Goals (SDGs)-2030.
