From: The effect of intermittent preventive treatment on anti-malarial drug resistance spread in areas with population movement

Figure 2

No movement - effect of IPT coverage. Model results without movement, p12 = p21 = 0, showing the effect of increasing IPT coverage with SP on the percent increase of R1 relative to RS and R2 relative to R1 resistance. Graph (a) represents the rate of spread (in percent) of R1 relative to RS parasites, while graph (b) represents that of R2 relative to R1. The parameter p12 is the rate of movement from the high malaria transmission area to the low transmission area, and p21 is the rate from the low transmission area to the high transmission area.
