Redefining public health and sustainable economy: Covid-19 from pandemic to endemic.

With the recent claim that the maintenance of population immunity will not depend on continued vaccinations but on the endemic presence of the virus, the proper understanding of the value of public health allows us to configure human living conditions as it thrives in a world where the novel Corona Virus Disease in 2019 (Covid-19) becomes endemic. World leaders and economic managers need to redefine public health not just as a means that enables economic productivity but as a substantially primordial goal-an end that every functional society must achieve via living an economically sustainable lifestyle. This paper argues that economic and societal sustainability thus must be framed and delimited within the human ecological boundary-a crucial viewpoint that could sustain public health amid a Covid-19 endemic world while preventing another viral pandemic from occurring.
