  In November 2015, El Salvador reported their first case of Zika virus (Zv)
leading to an explosive outbreak that in just two months had over 6000
suspected cases. Many communities along with national agencies initiated the
process to implement control measures that ranged from vector control and the
use of repellents to the suggestion of avoiding pregnancies for two years, the
latter one, in response to the growing number of microcephaly cases in Brazil.
In our study, we explore the impact of short term mobility between two
idealized interconnected communities where disparities and violence contribute
to the Zv epidemic. Using a Lagrangian modeling approach in a two-patch
setting, it is shown via simulations that short term mobility may be beneficial
in the control of a Zv outbreak when risk is relative low and patch disparities
are not too extreme. However, when the reproductive number is too high, there
seems to be no benefits. This paper is dedicated to the inauguration of the
Centro de Modelamiento Matem\'{a}tico Carlos Castillo-Ch\'{a}vez at Universidad
Francisco Gavidia in San Salvador, El Salvador.
