Models 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.
