Mathematical analysis of a disease-resistant model with imperfect vaccine, quarantine and treatment

Abstract: In this paper, we develop a new disease-resistant mathematical model with a fraction of the susceptible class under imperfect vaccine and treatment of both the symptomatic and quarantine classes. With standard incidence when the associated reproduction threshold is less than unity, the model exhibits the phenomenon of backward bifurcation, where a stable disease-free equilibrium co-exists with a stable endemic equilibrium. It is then proved that this phenomenon vanishes either when the vaccine is assumed to be… Show more

“…This genetic mutation has been reported to be inborn. There are very few paper on resistant mathematical model, some of them are [25], [13] and [15] but the resistance was modeled on influenza and SARS which is quite different from HIV/AIDS. This still remains a biological research question needed to be answered.…”

“…But unfortunately, from (3), (where all model parameters are assumed positive) which shows that S ( t ) > 0. Consequently, following the same approach, we claim that the solutions S v ( t ), S uv ( t ), E ( t ), G Q ( t ), P Q ( t ), I ( t ), P T ( t ), G T ( t ) and R ( t ) are positive for all time t ≥ 0 [9, 21, 22].…”

“…The available works that examined the effects of resistance are (Jia and Xiao 2018 ; Khanh 2016 ; Rabiu et al. 2020 ), where all of them incorporated it in flu model which is very much different from this study. Uniquely, our model also incorporates time-dependent controls (government’s intervention in promoting and encouraging behavior change, intake of balanced nutritional supplementation and ART) to determine the best combination of strategies capable in dealing with the virus spread.…”
