Estimates of the force of infection (λ, summed across all serotypes) and R₀ obtained from catalytic models fit to dengue age-specific seroprevalence data.

<p>*We fit models with increasing number of parameters. Thus, while model A assumes that the force of infection has been constant historically, models B and C allow for periods with different transmission intensity.</p><p>^† p-value of a likelihood ratio test comparing model B vs. model A.</p><p>^γp-value of a likelihood ratio test comparing model C vs. model B.</p><p>Estimates of the force of infection (λ, summed across all serotypes) and R₀ obtained from catalytic models fit to dengue age-specific seroprevalence data.
