In this work we consider a variation of the SIR model where mutations of the pathogen are allowed. We discuss the appearance of an endemic phase using a mean-field approximation and solve the stochastic model using Monte Carlo simulations. We find that our model has three distinct phases and serves as an interpolation between the SIR and SIS models
