Alter the dynamics of an uninfected population. So, the number 0 doesn’t completely describe the dynamics from the model when the reinfection is incorporated, as was noted prior to by Feng et al. in [26]. In contrast to the model published by these authors, which utilizes a single parameter for exogenous reinfection, in our model we use two parameters connected to two attainable pathways of reinfection (reinfection of latently infected and reinfection of recovered individuals).This is a reason why our model shows a extra SC1 biological activity complicated and richer dynamics. We’ve showed by way of theoretical evaluation in Section three and numerical simulations in Section four that if we accept as valid the plausible assumption that exposure toComputational and Mathematical Methods in Medicine5 0, 0, 30 0, 0 (1 ) 0 0 3 0, 0 0 1(a) 0 =0 three(b) 0 = 1.30 0 1(c) 0 = 1.0 3(d) 0 = 2.Figure 15: Indicators of coefficients , , and discriminant = 2 – 3 as functions of exogenous reinfection price of latent and exogenous reinfection rate of recovered for 0 1.

For 0 = 1 occurs a transcritical bifurcation from which emerges an endemic steady state. Additionally, based on Lemmas three and 4, any values of reinfection parameters within this parametric regime: (, ) [0, 1] 0, 1] would bring about the same qualitative dynamics and will not have an effect on this already classical behavior in SEIR models. In this case only one of many aforementioned arrangements(0 ) emerges as valid under this biologically plausible situation. Because the two parameters connected to exogenous reinfection of latently infected and recovered men and women do not impact the worth with the number 0 , even below the plausible assumption of partial immunity, variation of reinfection parameters could make that for the exact same worth of the quantity 0 , the top quality of dynamics along with the quantity of affected by illness men and women (incidence and prevalence) drastically alter. One example is, Figures five and 7 show two types of dynamics, 
that is, convergences to unique stationary points, a focus plus a node for the identical basic reproduction number 0 .

Taking less plausible assumption, but currently evidenced in quite a few works [5, 21, 22, 26], of an elevated susceptibility to reinfection over major infection in some situations leads us to a additional study of model (1).
