GUERRERO-FLORES, Shaday; OSUNA, Osvaldo    VILLAVICENCIO-PULIDO, Geiser. Existence of periodic solutions for seasonal epidemic models with quarantineExistencia de soluciones periódicas para modelos epidemiológicos estacionales con cuarentena. []. , 36, 1, pp.37-47. ISSN 0120-419X.  https://doi.org/10.18273/revint.v36n1-2018003.

In this work, we establish the existence of periodic orbits for a seasonal saturated epidemiological model of a population consisting of susceptible, infectious and quarantined individuals (an SIQS model). To do so, we use Leray-Schauder degree theory. We also provide numerical examples of these solutions.
