Generalized Models of the Seir Epidemiological Model and Their Discrete Analogues

The paper considers a discrete analogue of the SEIR model, which, unlike SIR, includes a group of infected individuals in the incubation (latent) period. This model is based on Lotka Volterra mappings operating in a three-dimensional simplex with degenerate skew-symmetric matrices, which correspond to mixedgraphs.Themodelsconsideredinthispaperareintended to study the course of viral diseases transmitted by the air-capillary route without a repeated effect.
