This notion has proven difficult for governments, though.  Many governments instead have started to decentralize/dismantle their programs because once Chagas disease became less of a health problem, the importance of continuing funding, surveillance, research, blood screening, et cetera became less appreciated and instead focus turned to more pressing health issues.  Making Chagas disease a lower political priority has been shown to cause it to come back from remission, though, and make previous efforts seem futile.
