From: Simulation-guided design of serological surveys of the cumulative incidence of influenza infection
Theoretical epidemic generated using an SIR model. LHS numbers of susceptible, infectious and recovered individuals over time. RHS Incidence of infection and incidence of seroconversion (assuming 90% of individuals seroconvert after 7 days). All model solutions use a reproductive number of R=1.4, a mean generation time T g =2.6 days, and are seeded at time t=0 with a single infectious individual. Scenario A, parts A and B, occurred in a population size of 100,000 individuals. Scenario B, parts C and D, occurred in a population size of 1 million. Scenario C, parts E and F, occurred in a population size of 10 million.
