Responding to COVID-19: What's the Problem?

This commentary argues that the coronavirus SARS-CoV-2 pandemic should be considered as a transdisciplinary societal challenge that requires coordinated systemic thinking and actions in the context of uncertainty. Responses to the propagation of the coronavirus SARS-CoV-2 and the health, economic and social impacts of Covid-19 are complex, emergent and unpredictable. We describe the virtuous relations between three prerequisite conditions-multilevel governance, knowledge and types of resources and individual and collective behaviours-that should be combined in transdisciplinary responses.
