From malaria to transfusion-induced malaria.

Malaria is still a blood transmissible disease, though its frequency is con tinuously decreasing in non endemic countries. In endemic areas, the number of infected subjects is either stable or increasing, depending on the invo lved country. Cases of imported malaria, particularly malaria due to Plasmo dium falciparum, are increasing in France. In regard to prevention in blood donors, regulations aiming at excluding potentially contaminated donors we re implemented with positive effects. Since 1994, no cases of malaria have been reported by the French organization of hemovigilance. (C) 1999 Elsevie r, Paris.
