(a) true unweighted epidemic costs Che = direct health cost of the epidemic, Cec = indirect (economic) costs, Che + Cec = total (unweighted) costs as functions of parameter \(\Lambda\) reflecting prioritization for indirect costs. (b) the corresponding weighted costs \((1-\Lambda )\) Che, \(\Lambda\) Cec, C=\((1-\Lambda )\) Che+ \(\Lambda\) Cec, also drawn as functions of \(\Lambda\).
