The effect of transition rate ${\beta }_1$ on (a) susceptible individuals (b) asymptomatic infected individuals, (c) unreported symptomatic infected individuals, (d) reported symptomatic infected individuals (e) recovered individuals, in computational simulations using MATLAB parameters used ${\beta }_1=4.5\times 10^{-7}$ for blue lines, ${\beta }_1=1.2\times 10^{-7}$ for green lines and ${\beta }_1=5.2\times 10^{-8}$ for red lines.
