[A system of simulation models of the epidemic process based on a socioecological concept].

In this paper different methods of modeling the epidemic process for different types of infectious diseases are discussed. We propose a concept of modeling for an essentially nonhomogeneous human population, taking into account biological, ecological and social factors. The method of an "epidemiological tree" has been developed, which makes it possible to divide the population into so-called "epidemiologically active groups".
