In order to define the epidemiological profile of the Human T-cell Lymphotropic Virus
(HTLV-1 and HTLV-2) among inapt blood donors population, at the HEMOPA
Foundation, in Belém, state of Pará, we analyzed 113 epidemiological forms, related
with risk factors associated with these retrovirus transmission, among carriers and noncarriers
of HTLV. We observed that 76% (n=50) of the inapt blood donors were
infected by HTLV-1 and 24% (n=16) by HTLV-2; 62% (n=70) of the carriers were
male and 38% (n=43) were female, with a tendency of infection in this gender
(p=0,007). The risk factors which exhibited significant results were: have received
blood transfusion (p=0,0003), more specifically to HTLV-2 (p=0,02); have been breastfeeding
from non-mother (p=0,006), more specifically to HTLV-1 (p=0,04); have been
submitted to surgery (p=0,01), discriminately to HTLV-1 (p=0,03) and HTLV-2
(p=0,04); share blades/shavers (p=0,02), more specifically to HTLV-1 (p=0,02); do not
use condoms during sexual intercourse (p=0,0003), discriminately to HTLV-1
(p=0,001) and HTLV-2 (p=0,002). Despite of the diverse stages existing in the process
of selection of blood donors, which the main objective is to eliminate potentials
candidates carrying transmissible blood diseases, in special of chronic and
asymptomatic course, exist bias that disable an exempt process of fails.
