Antibodies to HTLV-I p24 in African and Portuguese populations.

Using a radioimmunoassay to detect HTLV-I protein antibodies of molecular weight 24,000, we screened populations from Algeria (140 subjects), Tunisia (442), Mali (69), Senegal (415), Uganda (135), the Central African Republic (77), the Congo (360), and Madagascar (193). Only four subjects were positive (1 from Senegal, 1 from Uganda, 2 from the Congo). This is a much lower figure than that found by others in Africa by the enzyme-linked immunosorbent assay technique. In addition, 319 Portuguese blood donors (46 of whom have lived in Angola or Mozambique) were screened using the same radioimmunoassay. All were negative.
