Triatoma infestans control in the Paraguayan Chaco: a SENEPA (National Vector Control Programme) worker sprays an infested household.
Vector control has substantially reduced Chagas disease incidence. Yet, the enzootic nature of Trypanosoma cruzi transmission cycles makes disease elimination impossible. Sylvatic vectors often reinfest insecticide-treated households, and continuous surveillance is key to sustained control. Vector surveillance systems are much more sensitive when the community gets involved in reporting suspect insects; thus, fairly simple participatory strategies can critically enhance Chagas disease vector control (see Abad-Franch et al., doi:10.1371/journal.pntd.0001207).
