Abstract

Blood donor samples (1,007) were assessed for anti-phenolic glycolipid 1 (PGL-1) IgM antibodies and Mycobacterium leprae DNA presence, which had 3.8% and 0.3% positivity, respectively. After a 5-year follow-up period, six individuals with positive markers developed leprosy, raising the hypothesis that asymptomatic infection among blood donors may be an undisclosed mode of leprosy transmission via transfusion.
