Resumen
- The foot-and-mouth disease is a contagious viruses that plays an important role in the international cattle commercialization. This article aims stabilized finite element approximations for the spatial movement of a population infected by the footand-mouth virus in a healthy beef zone. The biomathematical model adopted gives rise to a spatial boundary-value problem which includes dispersive and migratory and mortality/natality effects. The numerical simulations performed have attested the instability of the Galerkin method when subjected to high migratory fluxes and deathrates.
