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




epidemics, models, statistics, chaos, complexity, dynamics, extensivity, relaxation, contagion, systems, mathematics, propagation


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.
