This paper derives approximations and bounds for the mean duration time of a simple epidemic in a population of individuals i = 1,. . . , IV, each of whom haa a specific susceptibility ai to infection, and a specific infectivity pi once infected, starting from an initial infective with infectivity P
The differential susceptibility SIR epidemic model with stage structure and pulse vaccination is introduced. By the comparison theorem, some sufficient conditions for the globally attractivity of an infection-free periodic solution and the permanence of this system are presented. Two numerical simul
apply the next-generator operator concept to the analysis of nondisease free equilibrium points in multigroup models in infectious diseases. In particular, we apply our results to the analysis of the local stability of a multigroup SEIR model.
