| description | Chagas disease is a complex clinical entity caused by a
protozoan parasite, Trypanosoma cruzi, transmitted by
the bite of infected triatomines. The objective of this study
was to establish the distribution of vector species of T. cruzi
according to all the geopolitical regions of Ecuador. This
narrative review was conducted from December 2022 to
July 2023 by searching the following databases: PubMed,
Elsevier, Google Scholar, Scielo, Latindex, and Dialnet. Also,
websites of international and national health organizations:
WHO and PAHO, Epidemiological Gazette of Ecuador,
SIVE-ALERTA, Ministry of Public Health of Ecuador, and
national repositories of theses generated by Ecuadorian
universities. In the Coastal region, T. dimidiata was found as
the predominant vector (83%), followed by Panstrongylus
howardi, P. chinai and P. geniculatus, all with the same
percentage of circulation (33%) and Rhodnius ecuadoriensis
(17%). In the Andean region, the most important species
was R. ecuadoriensis in the Province of Loja (59%). The
province of Orellana (Amazon region) had the highest value
of R=0.471 and greater species diversity (P. geniculatus, P.
lignarius, R. robustus, R. pictipes, R. pallences, R. barreti, E.
cuspidatus, E. mucronatu). Currently, the circulation of 4
genera and 17 species of triatomines is reported in Ecuador.
It is necessary to expand the collection sites in different
regions to update the geographical distribution of triatomine
species circulating in Ecuadorian territory. |
