报告摘要：Previous work has failed to fit classic epidemic models satisfactorily to the prevalence data of the famous English boarding school 1978 influenza A/H1N1 outbreak during the children’s pandemic. We built a susceptible (S) - exposed (E) - infectious (I) - confined to bed (B) - convalescent (C) - recovered (R) model with time delay in E and I compartments and multistage in B and C compartments. We simultaneously fitted the reported B and C prevalence curves as well as the attack rate (proportion of children infected during the outbreak). The model is based on delay differential equations and dummy subgroups to reproduce the non-exponential residence times, which was crucial for good fits. The estimates of the generation time and the basic reproductive number (R0) appear to be biologically reasonable. Our model has laid a base for further studies.
