  A two-patch mathematical model of Dengue virus type 2 (DENV-2) that accounts
for vectors' vertical transmission and between patches human dispersal is
introduced. Dispersal is modeled via a Lagrangian approach. A host-patch
residence-times basic reproduction number is derived and conditions under which
the disease dies out or persists are established. Analytical and numerical
results highlight the role of hosts' dispersal in mitigating or exacerbating
disease dynamics. The framework is used to explore dengue dynamics using, as a
starting point, the 2002 outbreak in the state of Colima, Mexico.
