Globally, public health is increasingly acknowledged as a separate academic field. Nevertheless, there are little chances for study, research, and practise in this area in India. Started public health practice has seen some alterations as a result of the shifting needs of the global communities from roughly two centuries ago. Considering the historical context that gave rise to this distinct field of study and practise by incorporating pertinent facets of the humanities and technical innovations of the natural sciences, especially from the engineering and biomedical sciences, a critical review of the principles, core values, and approaches of public health is necessary to address the social needs of the present and to serve the demands that may emerge in the future.
