Resource Allocation for Epidemic Control in Metapopulations
Figure 1
Comparison of disease progress curves for a strategy that gives preferential treatment to the more infected sub-population (A,D,G), preferential treatment to the less infected sub-population (B,E,H) and the most efficient strategy (C,F,I).
Disease progress is shown for different control outcomes. (A–C) Progress of disease in two interconnected regions 1 (solid lines) and 2 (dashed lines), with treatment dynamics in insets, showing little differences between control strategies. (D–F) Preferential treatment to the more infected sub-population and preferential treatment to the less infected sub-population diverge markedly from the most efficient strategy. (G–I) Disease continues to increase but markedly less steeply in the region with the lower infestation (region 2), for preferential treatment to the less infected sub-population and most efficient strategy. Disease progress curves are given for three different values of the initial number of infected: (A,B,C), (D,E,F), and (G,H,I). Default parameters are (efficiency of control),
(within-region transmission rate),
(coupling strength),
(recovery rate),
(rate of loss of immunity),
(rate of birth/death),
(discount rate), and
(fixed expenditure limit).
