Dynamics of SIR Model with Saturated Treatment Function under the Effect of Pollution
Abstract
This paper studies SIR model with incidence rate which is saturated and nonlinear. We have considered saturated treatment function on a logistically growing population. Boundedness of the system has been obtained along with existence of disease-free and endemic equilibrium points. We deduce that the strict threshold for illness obliteration is weak when the basic reproduction number approaches unity. The global stability of the endemical equilibrium point is established using Lyapunov Lasalle theorem. Condition for Persistence of endemicity of our model has been discussed. Mathematically this paper recommends that keeping the atmosphere clean, building healthy relation with nature, giving timely treatment to the patients by increasing the equipment and capacity of hospitals, improving the cure
efficiency are all valid methods for managing the disease. Numerical simulations are shown that exhibit results obtained analytically.

Disclaimer/Regarding indexing issue:
We have provided the online access of all issues and papers to the indexing agencies (as given on journal web site). It’s depend on indexing agencies when, how and what manner they can index or not. Hence, we like to inform that on the basis of earlier indexing, we can’t predict the today or future indexing policy of third party (i.e. indexing agencies) as they have right to discontinue any journal at any time without prior information to the journal. So, please neither sends any question nor expects any answer from us on the behalf of third party i.e. indexing agencies.Hence, we will not issue any certificate or letter for indexing issue. Our role is just to provide the online access to them. So we do properly this and one can visit indexing agencies website to get the authentic information. Also: DOI is paid service which provided by a third party. We never mentioned that we go for this for our any journal. However, journal have no objection if author go directly for this paid DOI service.
