Fig. 2From: Operational strategies of anti-malarial drug campaigns for malaria elimination in Zambia’s southern province: a simulation studyAssumptions about the decay in drug effectiveness. ACT (dashed/dotted lines) decay in a step-wise fashion with AL (green) lasting 25 days and DHAP (purple) 35 days. PQ (solid line) has an exponential decay with varying half-life of effectiveness of 12 (gray), 48 (blue), and 72 h (orange). Ivermectin (dashed lines) smoothly decays to efficacy of zero after 2 (red), 4 (grey), and 7 days (brown)Back to article page
