Propagation of SARS-CoV-2 in Cuba. A qualitative viewpoint from the complex systems theory

Abstract

We describe some properties of the evolution of the COVID-19 pandemic that reveal its behavior as a complex system. The propagation mechanism shows a Poincaré section with fractal dimension 1 < D < 2. The present period of apparent recovery shows a relaxation with non-extensive statistical properties.
