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 = p
12
/ p
21 = 1, p
12 = 0.01) is considered. The parameter p
12 is the rate of movement from the high transmission area to the low transmission area, and p
21 is the rate from the low transmission area to the high transmission area, , is the ratio of the high transmission population to that of low transmission population.
