Contribution

It introduces a stochastic model with protection awareness, analyzes its stability and extinction conditions, and compares effects of publicity strategies and ART in controlling HIV/AIDS.

Findings

Protection awareness significantly affects AIDS control.

Continuous ART helps reduce HIV/AIDS prevalence.

Numerical simulations support theoretical stability results.

Abstract

We establish a stochastic HIV/AIDS model for the individuals with protection awareness and reveal how the protection awareness plays its important role in the control of AIDS. We firstly show that there exists a global positive solution for the stochastic model. By constructing Lyapunov functions, the ergodic stationary distribution when $R_{0}^{s}>1$ and the extinction when $R_{0}^{e}<1$ for the stochastic model are obtained. A number of numerical simulations by using positive preserving truncated Euler-Maruyama method (PPTEM) are performed to illustrate the theoretical results. Our new results show that the detailed publicity has great impact on the control of AIDS compared with the extensive publicity, while the continuous antiretroviral therapy (ART) is helpful in the control of HIV/AIDS.
