Figure 3From: Simulation-guided design of serological surveys of the cumulative incidence of influenza infection Simulated study estimates of cumulative incidence of infection with population size 1 million. Red line shows the SIR model cumulative incidence. Green line shows the 95% confidence intervals of cumulative incidence estimates from a longitudinal design and blue lines the 95% confidence intervals of cumulative incidence from a cross-sectional design. A,B,C, and D correspond to Scenarios A,B,C, and D (see Figure 2 and main text).Back to article page
