Abstract: Pandemics are unique and transformational events as they shake lives by exposing the vulnerability of Homo sapiens to previously unknown pathogens, which become widespread as most human beings on the planet will become infected. But Covid-19 has done much more than this. It has exposed us to another type of vulnerability – the vulnerability of the systems we operate in. It has also opened our eyes to the harsh reality that we live in a closed system, in which we are entirely interconnected and interdependent with other creatures on planet earth. This awareness has paved the way to acknowledge that as a society we should embrace the One Health approach which recognizes the links between the health of humans, animals, and the environment. 
Covid 19 has also shown us that such a major health crisis has multiple drivers and ramifications that include social, economic, and digital drivers that have caused the pandemic to unravel in the way it did. In addition Covid 19 is the most measured event in history and oceans of big data have been generated during this event.
Since the turn of the millennium we have been experiencing several other challenges which concern our closed system and affect our health, for instance the climate and food crises. For example, we are aware of the devastating effect of rising temperatures on the health of our oceans, on the loss of biodiversity and on the migration of humans and animals. We are also well aware that the planet’s demographics will require more food to feed a world population expected to reach 9.7bn by 2050 and at the same time we have committed to diminishing greenhouse gas emissions to reduce pollution and CO2 footprint.
Following the conceptual blueprint of Circular Economy and Circular Agriculture, this  could be the right time to expand our approach to health to a circular model which encompasses the intricate and novel links between human health and the health of this closed system. This circular approach would be data driven and could be implemented by using the Sustainable Development Goals (SDGs) roadmap as an accelerator of convergence for health. All the 17 goals have ties to the health of humans, animals, plants, and the environment, and it would seem reasonable to prioritize certain activities and capitalize on existing guidelines and commitments.
The novelty of the Circular Health approach is to use post-Covid-19 renewed health priorities to promote the convergence of health-related issues which can be achieved within the Sustainable Development Goals framework. In this way it will be possible to advance urgent health priorities within an existing framework which aims at sustainability and at advancing health as an essential resource within a closed system, which needs to be regenerated and addressed in its complexity.
