  In the present article a mathematical model is proposed to research the
current coronavirus outbreak (SARS-CoV-2) in Paraguay, describing the multiple
transmission paths in the infection dynamics, following the susceptible,
exposed, infectious, hospitalized, with lost immunity and recovered
individuals, as well as the role of the virus in the environment and deaths
from COVID-19 or other reasons. In order to reflect the impact of the control
measures adopted by the government and the population, the model employs
variable transmission rates that change with the epidemiological status and
environmental conditions. The model is validated, and its application is
demonstrated with data publicly available.
