Among the many efforts done by the scientific community to help coping with the
COVID-19 pandemic, one of the most important has been the creation of models to
describe its propagation, as these are expected to guide the deployment of
containment and health policies. These models are commonly based on exogenous
information, as e.g. mobility data, whose limitedness always compromise the
reliability of obtained results. In this contribution we propose a different
approach, based on extracting relationships between the evolution of the disease
in different regions through information theoretical metrics. In a way similar to
what is commonly done in neuroscience, propagation is understood as information
transfer, and the resulting propagation patterns are represented and studied as
functional networks. By applying this methodology to the dynamics of COVID-19 in
several countries and regions thereof, we were able to reconstruct static and
time-varying propagation graphs. We further discuss the advantages, promises and
open research questions associated with this functional approach.
