Figure 1From: Measurement of Plasmodium falciparum transmission intensity using serological cohort data from Indonesian schoolchildrenModels for the transitions between serological states. Two models for the transition of individuals from positive (top row) to negative (bottom row) serological states over the course of the study: Model 1 assumes one positive and one negative state, with conversion rate λ and reversion rate ρ. Model 2 treats individuals separately which are already seropositive at the start of the study. Those revert at a rate γ, which may be different from ρ. Titre distributions in positive and negative individuals are schematically indicated on the left.Back to article page
