## Cumulative and maximum epidemic sizes for a nonlinear SEIR stochastic model with limited resources

Received  March 2017 Published  September 2017

The paper deals with a stochastic SEIR model with nonlinear incidence rate and limited resources for a treatment. We focus on a long term study of two measures for the severity of an epidemic: the total number of cases of infection and the maximum of individuals simultaneously infected during an outbreak of the communicable disease. Theoretical and computational results are numerically illustrated.
