Usefulness of serology for the evaluation of Trypanosoma cruzi transmission in endemic areas of Chagas' disease
Thirteen communities from 7 Argentinian provinces were selected for the evaluation of serology as an indicator of transmission of Chagas disease. Of the communities appraised, 6 did not have a history of previous treatment with insecticides and 7 had received sporadic or continuous insecticide treat...
