How to Minimize the Attack Rate during Multiple Influenza Outbreaks in a Heterogeneous Population
Broken line: susceptible; solid line: infected. CAAW: Cumulative attack rate (adults, with whole population as the denominator); CACW: Cumulative attack rate (children, with whole population as the denominator). Infection was re-introduced into the population on day 300. The intervention (fAA = fAC = fCA = fCC = 1) started on day 100 (when the children’s epidemic is at its peak) and lasted until the first outbreak was over. βAC = βCA = 0; R0A = 1.25; R0C = 2. 50% adults; 50% children. All other parameters and initial conditions are listed in Tables 1 and 2.
