摘要: This paper mainly investigates dynamics behavior of HIV (human immunodeficiency virus) infectious disease model with switching parameters, and combined bounded noise Gaussian white noise. is different from existing models. Based on stochastic It? lemma Razumikhin-type approach, some threshold conditions are established to guarantee the eradication or persistence. Results show that smaller amplitude R?0 1 Moreover, it found larger intensity suppresses prevalence even if > 1. Some numerical examples given verify obtained results.
