This analysis reveals conditions for disease extinction and persistence in a stochastic SVIR model, indicating potential public health implications.
In this work, a stochastic delayed SVIR (susceptible-vaccinated-infected-recovered) model with logistic growth of population, saturated incidence function and distributed delay is analyzed. The sufficient conditions for the extinction and persistence in mean of the disease and existence of a stationary distribution are obtained. The theoretical results are illustrated via numerical simulations.
