Abstract
Certifying the absence of Chagas disease transmission by native vectors lacks scientific grounds and weakens long-term control-surveillance systems to the detriment of people living under risk conditions. Instead, a regular "certification of good practice" (including vector control-surveillance, case detection/patient care and blood safety) could help achieve sustained disease control.
Highlights
Chagas disease vector control is among the greatest public health achievements ever
Certification was intended to recognise the huge efforts made by Governments and international agencies to achieve the specific goal of interrupting transmission by these non-native vectors
Native vector populations, which occur in natural ecotopes across their geographic ranges, pose a radically different problem; here we argue that certification of interruption of transmission has no role to play in this case and question who is likely to benefit from such a certification policy
