OSUNA, OSVALDO  e  VILLAVICENCIO-PULIDO, GEISER. The simultaneous application of control interventions can lead to catastrophic epidemic scenarios. Integración - UIS [online]. 2021, vol.39, n.2, pp.177-190.  Epub 18-Abr-2022. ISSN 0120-419X.  https://doi.org/10.18273/revint.v39n2-2021003.

We analyze the evolution of an infectious disease if infectious individuals are treated or isolated. The analysis of the model shows catastrophic scenarios for the population in which bringing R 0 below 1 is not enough to decrease the number of infectious individuals. Finally, we show three scenarios for the behavior of the model solutions in which multiple endemic equilibria exist.
