  1. Column 1 identifies the country of origin for the samples; results of the TrV sera analyses. Numbers in columns 47 indicate the number of serum samples employed in each analysis. ELISA assay 1 corresponds to reactivity against structural proteins, and ELISA assay 2 corresponds to reactivity against the non-structural protein RdRp. WB refers to immunoblotting analysis against the structural proteins of TrV. RT-PCR refers to reverse transcriptase-PCR*. Cuba is a non-endemic country for Chagas disease. #The sera from Portugal are imported case of Chagas disease, mainly from Brazil.
