โœฆ Synopsis

An SIS epidemic model with maturation delay is analysed. It is shown that the disease dies out when the basic reproduction number R -1, and the disease 0 remains endemic when R ) 1 in the sense of uniform persistence. When the 0 disease induced death rate is sufficiently small, the global attractivity of the endemic equilibrium is also proved.

In this paper, a non-autonomous SIRVS epidemic model with time delay and vaccination is investigated. We assume that the vaccinated have a constant immunity period. Some new threshold conditions are obtained. These threshold conditions govern the extinction and permanence of the disease. When the mo

We present a simple epidemic model representing the spread of a communicable disease in a spatially extended host population. The model falls into the general class of techniques which utilise lattice based simulation as a way of incorporating spatial effects. The factors relating to the persistence
