Abstract:
2329 subjects (blood donors and patients) from various areas of the Sultanate of Oman were investigated for the presence of HTLV-I antibody by as enzyme immunoassay (EIA) method. 10 subjects (0.4%), including 9/1586 blood donors (0.6%) and 1/165 patients with sexually transmitted diseases (0.6%), were found to be EIA seropositive with a regional variation in seroprevalence of 0-14%. 6/9 EIA seropositive samples from blood donors yielded 'indeterminate' results on Western immunoblot analysis (WBA). A much larger survey with additional confirmatory assays such as a radioimmunoprecipitation assay (RIPA), should provide a more conclusive picture of the prevalence of this retroviral infection in the Sultanate.
