Asymptomatic Leishmania infections have been the main cause of transfusion transmission in endemic areas. Polymerase chain reaction has been used to detect L. infantum DNA in the peripheral blood of asymptomatic Leishmania carriers. In our region, the prevalence of asymptomatic L. infantum infection in donors is markedly high (5·9% of donors studied). We investigated the ability of pathogen inactivation technology, using amotosalen and UVA illumination, to eliminate L. infantum in a blood component collected from an asymptomatic L. infantum infected donor. This is the first report of the INTERCEPT system being used to eliminate a parasite from a component collected from a donor.
