Despite deinsectization campaigns conducted in many Latin American countries, bugs called Triatoma infestans, the main vector species for Chagas' disease, are now reappearing in villages in several regions. Wild populations of Triatoma infestans are recolonizing dwellings. The latter seem very close genetically to their domestic congeners and therefore, like their domestic counterparts, are able to adapt to humans. These wild bugs thus represent a significant risk for the re-emergence of Chagas' disease, as one out of two has been shown to carry the parasite responsible for the infection.
