Symmetric movement - effect of IPT coverage for 1 day stay. Model results with symmetric movement and equal population sizes for 1 day visitation (p₂₁ = 1, p₂₁/p₁₂ = 1 = m) showing the effect of increasing IPT coverage with SP on the percent increase of R1 relative to RS (Graph (a)) and R2 relative to R1 resistance (Graph (b)).
