About two compared SEIADR and SEIR discrete epidemic models

Abstract

This paper obtains and studies discrete epidemic models of SEIADR (susceptible-exposed-asymptomatic infectious, symptomatic infectious, recovered, or immune, and dead-infective corpses) and SEIR continuous-time models. The first one incorporates the asymptomatic infectious and the lying infective bodies as infectious extra populations on the standard populations of SEIR type models. Several controls are proposed in the general case as, for instance, vaccination treatment and the removal of the infective lying corpses. The controls can include feedback information.
