A Comparison Between SEIADR versus SEIR Discrete Epidemic Models

This paper proposes, studies and discusses in some detail discrete epidemic models of SEIADR (susceptible-exposed-symptomatic infectious- asymptomatic infectious-recovered, or immune- dead- infectious-recovered) and SEIR (susceptible-exposed-symptomatic infectious-recovered) continuous in 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 lying infective corpses. The control rules can optionally include feedback information.
