Table 1 Positive and negative sera for Triatoma virus by country of origin resulting from different types of analysis

Country	Sera analysed	Chagas patients (%)	ELISA 1 positive	ELISA 2 negative	WB positive	RT-PCR negative	Negative control
Argentina	122	40	41	50	36	50	12
Bolivia	117	68	11	-	-	-	20
Brazil	50	100	0	-	-	-	22

Column 1 identifies the country of origin for the samples; results of the TrV sera analyses. Numbers in columns 4–7 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.
