Abstract
The structure-preserving features of the nonlinear stochastic models are
positivity, dynamical consistency and boundedness. These features have a significant role
in different fields of computational biology and many more. Unfortunately, the existing
stochastic approaches in literature do not restore aforesaid structure-preserving features,
particularly for the stochastic models. Therefore, these gaps should be occupied up in
literature, by constructing the structure-preserving features preserving numerical
approach. This writing aims to describe the structure-preserving dynamics of the
stochastic model. We have analysed the effect of reproduction number in stochastic
modelling the same as described in the literature for deterministic modelling. The usual
explicit stochastic numerical approaches are time-dependent. We have developed the
implicitly driven explicit approach for the stochastic epidemic model. We have proved
that the newly developed approach is preserving the structural, dynamical properties as
positivity, boundedness and dynamical consistency. Finally, convergence analysis of a
newly developed approach and graphically illustration is also presented.
