Abstract
Pandemics are becoming a recurring threat to our global society. Henceforth it is of paramount importance to provide reliable and simple mathematical modelling of their spread to guide decision makers and healthcare stakeholders. We review a novel symmetry-based analysis of epidemiological data, based on ideas adapted from theoretical physics, also known as the epidemiological Renormalization Group (eRG) framework. One major result is the first consistent mathematical modelling of multi-wave patterns, which have been observed in infectious disease spread. Thanks to the plethora of data available for COVID-19, we studied the evolution of variants via an unsupervised machine learning approach of the spike protein genome. With the use of the eRG framework, we confirmed that the emergence of new virus variants is one of the major causes of the onset of a new wave. This result can shape the best strategy to control and tame ongoing and future pandemics.
