SUMMARY:
Since 1990, epidemic spread has been the subject of many studies based on sta- tistical physics methods. The dynamics of these epidemic processes, typically of non- equilibrium, consist of competition for active (infected hosts) and inactive (uninfected hopedeiro) health status. The transition between these active (epidemic) and inactive (non-epidemic) states allows the analysis of the critical point and exponents of the sys- tem (universality class). In this thesis, the critical properties of two epidemic systems are investigated: The first compound of two population species that are human with uninfec- ted hosts (H) and infected hosts (Hi) and that of vectors composed of non-infected vectors infected (V ) and infected vectors (Vi), which spread independently in a one-dimensional network, at D rates, following a dynamic probability rule, where the cure rates of vectors and individuals are respectively φ and λ. A second epidemic system, known as suscep- tible infected susceptible (SIS), in a complex network with high aggregation factor and contamination rate λ. For both models, computer simulations are used using the Monte Carlo Method to obtain the data and perform a finite-size scale analysis to estimate cri- tical properties. The conclusion of this work is the analysis of critical points and critical exponents. It is expected to define a new class of universality and a parallel with the methodology used by epidemiology to combat infectious diseases.
