Numerical simulation of SEIR model \(\left(1\right)\) by using NSFD scheme with \(\left( {\mathbf{a}} \right)\,h = 0.01,\left( {\mathbf{b}} \right)\,h = 1,\left( {\mathbf{c}} \right)\,h = 20,\left( {\mathbf{d}} \right)\,h = 50\). Remaining parameters are set as \(\varphi = 4.5,\tau = 0.0{99925},\psi = 0.02,\theta = 0.1503,\alpha = 0.0125,\delta = 0.625,\sigma = 0.125.\)
