Travel-related health issues

Severe imported malaria is an important problem in many countries in which this disease is not endemic. This retrospective study describes the characteristics of 20 adults with severe imported malaria admitted to our intensive care unit from 1991 through 2007. All episodes were caused by Plasmodium falciparum and all patients had returned from sub-Saharan Africa, except for one transfusion recipient. All persons were considered non-immune, and none had taken appropriate chemoprophylaxis. The median time between the initiation of symptoms and the diagnosis was seven days. Five patients died (mortality rate = 25%). A higher frequency of unrousable coma and acidosis and a higher median Apache II score at admission was noted in the persons who died. Mortality by severe malaria remains high despite high quality management, which highlights the importance of chemoprophylaxis and early diagnosis and treatment.
