Optimal control levels (a) an associated control costs (b) as a function of population’s current \(R_{e}\) value for populations with 0% immunity. Solid lines correspond to strategies in which both controls can be applied at different levels on the low-risk and high-risk population subgroups, while dashed lines are for strategies in which the same control levels are applied to both subgroups
