A continuous cycle circles within the themes of health and development. With poor health, low productivity follows. And the other way around also applies.
Global development, in the sense of the word, had evolved from economic development to social development and then to the present, sustainable development. Not all the countries are on the sustainable phase but global efforts through several organizations are being done to help achieve progress in these developing countries, with more focus on health. Because ultimately, man and his health is both the means and end of development.
