Symmetric movement - effect of drug half-life for 100 days stay. Effect of IPT treatments with drugs with different half-lives, SP or CPG-DDS, on the increase percentage of R1 relative to RS in both a low (Graph (a)) and high (Graph (b)) transmission setting, when symmetric movement between equally sized populations (m = p₁₂/ p₂₁ = 1, p₁₂ = 0. 01) is considered. The parameter p₁₂ is the rate of movement from the high transmission area to the low transmission area, and p₂₁ is the rate from the low transmission area to the high transmission area, $m=\frac{N_H}{N_L}=\frac{p_{21}}{p_{12}}$, is the ratio of the high transmission population to that of low transmission population.
