Left: Asymptotic state of the scenario (i): average infection rate as a function of contagiousness β and infection probability p. Also shown is the critical line \(p(\beta )\) in (2) (black dashed line). “W” indicates the parameter set consistent with COVID-19 outbreak in Wuhan. Right: Dynamics of the rate of infected (red bars) compared with the asymptotic value of the field theory (SIS model), which bounds the maximum rate of infected agents
