Human infection with Trypanosoma cruzi in Nasca, Peru: A seroepidemiological survey (1)
We estimated the proportion of seropositivity for infection with Trypanosoma cruzi (Chagas’ disease) in a sample of the rural population of the Province of Nasca, Department of Ica, southwestern Peru. Although Triatoma infestans, the only vector species identified in the Department of Ica, is often...
