Mathematical model of virus disease morbidity evolution in communities with several components

Mathematical models previously developed for the evolution of virus disease morbidity in communities with a single component are generalized so as to be applied to the case of communities consisting of several coupled components. Epidemiological characteristics are discussed in the case of components linked by weak, strong or intermediate couplings. A detailed analysis is made of the cases when the different components are represented by; a) different geographical areas; b) different types of sources of infection; c) different age groups.
