aData from 1993 except for Ecuador and Paraguay, which were for 1994.
bNumber of cases transmitted by blood transfusion = [number of donors x P(I) ]. For calculations of number of infections, the prevalence was corrected taking into account the sensitivity of the screening.
cInfection spreading index = (total number of infections transmitted ¸ number of donors) x 10,000.
dFractionation index = 1.85.
eData not available.
fResidual infectivity considering that sensitivity of diagnostic tests is not 100%.
gFractionation index = 1.5.
