Low prevalence of antibodies to human T-lymphotropic virus-I/II among blood donors in eastern Saudi Arabia.
The seroprevalence of human T-lymphotropic virus (HTLV)-I/II was assessed in 13,443 consecutive blood donors in eastern Saudi Arabia between 1998 and 2001. Screening by enzyme-linked immunosorbent assay (ELISA) and confirmation by Western blot resulted in 8 (0.060%) positive cases, of which 5 (0.056%) belonged to Saudi and 3 (0.113%) to non-Saudi donors. The majority of the HTLV-positive donations (6/8) were for patients, and none had a history of known risk factor for HTLV-I/II transmission. Although the very low prevalence of HTLV-I/II among Saudi donors does not support routine screening, screening of donors from other nationalities may be initiated, especially those from HTLV-I/II endemic areas.
