Heterogeneities in Transmission and Epidemiology of Chagas Disease in Central America and Mesoamerica Appear Related to Evolutionary Divergences of the Main Triatomine Insect Vector.
Photograph showing an adult specimen of Triatoma dimidiata from Colombia. DNA sequences prove that this vector species has followed different evolutionary lines throughout its geographical distribution in Mexico, Guatemala, Honduras, Nicaragua, Panama, Colombia, and Ecuador. Speciation and subspeciation furnish a new frame to take into account for future control strategies (see Bargues et al., doi:10.1371/journal.pntd.0000233).
