Research Abstract |
The aim of this study was to predict the size and speed of the epidemic caused by a new subtype of influenza. A new influenza with the same force of infection as Asian flue (1957-59) was assumed to invade Japan in winter. The Kermack-McKendrickmodel was used for the computer simulation. The data for the estimation of the force of infection was taken from the reported number of influenza patients by the Japanese national surveillance of the infectious diseases and the number of death from the Japanese demographic survey. The temporal change in those numbers were assumed to reflect the number of infected persons. The result of the simulation assuming the worst setting shows that the cumulated incidence can be 75 % of the total population, the prevalence of the influenza infection may reach to 34 % of the total population, and the peak of the epidemic will come within 8 weeks after the invasion. Such a disastrous scenario should not be excluded from the consideration when preparing for the pandemic of influenza.
