Samples were considered positive if they tested positive by both TESA Western blot and Chagateck ELISA and may also be IHA positive. Samples were considered positive if their Cq value was equal or less than 39. Only three serum samples were obtained from healthy volunteers, all remaining samples were obtained from HIV positive individuals. Pos = positive, Neg = negative.
