Background: The COVID-19 pandemic represented a global earthquake that made the review of health policies aimed at strengthening common governance necessary.
Objective: The paper analyses the reasons for which the One Health approach has become fundamental in the control of pandemic phenomena, by arguing the necessity to place it at the basis not only of health policies but also of intersectoral policies.
Methods: The documents of the world organizations published before and after the pandemic were analyzed and studied in order to unpack the close relationship between new lifestyles and the increase of health risks.
Results: It emerged that the One Health approach is a paradigm that has been advanced for more than 30 years, but due to the inadequacy of local and world health policies, this approach was never translated into concrete actions to protect health, feeding problems at the cause of the COVID-19 pandemic.
Conclusions: Having ascertained that the adoption of a One Health approach can no longer be postponed, this must be insisted on several interconnected sectors that establish the new concept of healthcare which, in addition to being interdisciplinary, necessarily takes on a global perspective.
