Disease state transitions and groups represented in the static risk and individual-based models. a Disease transitions in the static risk model were limited to new infections and reactivation from existing latent infections, while the individual-based model also represented longer-term processes such as new infections contributing to prevalence (not shown). b Population mixing patterns as fraction of time per annum spent in a different community (for short-term mixing) or probability of residency change per annum (for longer-term migration). Both static risk and individual-based models represent short-term mixing, but only the individual-based model represents longer-term migration.
