dc.description.abstract | There are four vector species of Chagas disease in Chile: Triatoma infestans, responsible
for the domestic cycle; Mepraia spinolai, the main wild vector; and M. gajardoi and M. parapatrica,
two coastal wild species whose importance as vectors is not well known. They are
species of dry environments of the central-north region of Chile, whose best predictors
of distribution are warm average temperatures and low rainfall. They are found in rock
quarries, nests of birds, and small mammals, and T. infestans has sylvatic foci associated
with a Bromeliaceae species. While human blood represents 70% of the diet of T. infestans,
in M. spinolai this value is 7%, which means that a large part of Chagas disease in Chile
is due to T. infestans. However, all species have high percentages of T. cruzi infection.
Chagas disease in Chile follows the distribution of T. infestans, and although the cycle of
domestic transmission by this vector is interrupted, there is still a constant prevalence
and mortality and ascending incidences. Models predict that although climate change
will not vary greatly the north-south distribution of vectors, it could increase the reproductive
number of the disease, increasing risk areas of Chagas disease.
