Population responses in the absence of social distancing. Here $h_2\left(t\right)\equiv 0$, i.e. no social distancing has been implemented. We simulated the model introduced in Section 2.1 for 180 days. Note that the infected symptomatic population ($I$, solid red curve) comprises about $40\%$ of the population by day 30. Units of vertical axes are percentage of initial population.
