A stochastic model of initial HIV infection on lattice spaces

Original Article


A stochastic model based on the Nowak-May model for interaction between the human immunodeficiency virus (HIV) and the immune system is presented. From simulations with the stochastic model expressed on lattice spaces, an antigenic diversity threshold for HIV is shown. Mutation of HIV causes the antigenic diversity threshold to decline. However, most of the behavior in this stochastic model strongly depends on intial conditions.
