The effect of irreversible drug abuse in a dynamic model

Abstract

<p style='text-indent:20px;'>In this paper, we analyze a mathematical model of the SIER type which includes susceptible and infected and removed people. In this model, we compute <inline-formula><tex-math id="M1">\begin{document}$ {\mathcal{R}_1} $\end{document}</tex-math></inline-formula> in strain one and <inline-formula><tex-math id="M2">\begin{document}$ {\mathcal{R}_2} $\end{document}</tex-math></inline-formula> in strain two. Then we compute the equilibrium points and then determine the global stability.</p>
