A Fixing \(\lambda = 0.95\), we show the change in final epidemic size per community (community 1 on the left and 2 on the right) for different interventions (axes) and coupling strength (rows). B Fixing \(\rho = 0.02\), we repeat the experiment now varying the epidemic transmission rate (rows). Color scale goes from best outcome (eradication of epidemic) in dark blue, to no change in grey, to worst possible outcome (\(R(\infty ) = 1\)) in dark magenta. In both panels, we use a dashed area to highlight the regime of unintended consequences where a useful intervention in community 2 worsen the epidemic in community 1
