Abstract

Abstract:

Due to the influence of age or physical fitness, resulting in a number of susceptible to infection into the latent, some directly into patients, study of epidemic model so it is necessary to enter a latent or infected population proportion, but this kind of model is rarely taken into account the influence of age, study on the age structure of the infectious disease model of this change on the proportion of the total population in infected groups or latent, the expressions of the threshold parameters related to the population growth index are obtained, the existence and the local asymptotic stability conditions of the disease-free equilibrium and endemic equilibrium are discussed, then, the use of these conditions to control the spread of disease has important theoretical and practical significance.

Key words: Proportion, Varying population size, Spectrum
