Severe imported Plasmodium falciparum malaria, France, 1996-2003.

ABSTRACT: Little is known about severe imported Plasmodium falciparum malaria in industrialized countries where the disease is not endemic because most studies have been case reports or have included <200 patients. To identify factors independently associated with the severity of P. falciparum, we conducted a retrospective study using surveillance data obtained from 21,888 P. falciparum patients in France during 1996-2003; 832 were classified as having severe malaria. The global case-fatality rate was 0.4% and the rate of severe malaria was ≈3.8%. Factors independently associated with severe imported P. falciparum malaria were older age, European origin, travel to eastern Africa, absence of chemoprophylaxis, initial visit to a general practitioner, time to diagnosis of 4 to 12 days, and diagnosis during the fall-winter season. Pretravel advice should take into account these factors and promote the use of antimalarial chemoprophylaxis for every traveler, with a particular focus on nonimmune travelers and elderly persons.
