A stochastic SICA epidemic model for HIV transmission
arXiv:1805.01425 · doi:10.1016/j.aml.2018.05.005
Abstract
We propose a stochastic SICA epidemic model for HIV transmission, described by stochastic ordinary differential equations, and discuss its perturbation by environmental white noise. Existence and uniqueness of the global positive solution to the stochastic HIV system is proven, and conditions under which extinction and persistence in mean hold, are given. The theoretical results are illustrated via numerical simulations.
