Investigating the contribution of fractional index parameter $\left(\vartheta \right)$ on the disease dynamics with reduction in transmission rate as control measure (a) Susceptible individuals, (b) Exposed individuals, (c) Asymptomatic infectious individuals, (d) Symptomatic infectious individuals (e) Infectious individuals in isolation, (f) Recovered individuals. We use the parameter values in Table 1 and take $\rho =0.4$. With these values, ${\mathfrak{R}}_0=0.9077$.
