A Severe Case of Falciparum Malaria, 10 Years After Malaria Eradication: A Case Report

Malaria is a major mosquito-borne public health problem especially in tropical countries. The authors report a malaria infection in a 31-year-old man who had returned from East Africa with developed fever and rigor. Because of his thrombocytopenia, decreased hemoglobin, elevated liver enzymes, and splenomegaly, and because of failure to question about recent travel history, he was initially referred to the hematological hospital and medical staff suspected a hematological problem, so he was investigated for bone marrow aspirate and biopsy. As he progressively deteriorated, and after retaking history, his relatives eventually came to mention their travel to Africa. Blood samples were sent to detect malarial parasites, but the results were negative. When an internist was consulted, the patient was drowsy with low oxygen saturation (SpO2), so he was intubated and put on continuous positive airway pressure (CPAP). The internist suggested empirical anti-malarial treatment, which improved the clinical and hematological conditions of the patient. However, the repeated thin blood film showed falciparum malaria ring-shaped trophozoites. The patient persisted with the same treatment for 1 week until his condition improved gradually and completely stabilized, and then he was discharged. Presentation of this case of malaria is crucial to outpatient clinics’ proper referral of cases, as is encouraging the physician to think of malaria as a cause of fever and rigor even in countries with eradicated malaria and to insist on mentioning travel history. It is also imperative, in the case of sustaining fever with further deterioration of the patient after proper antibiotic use, to start empirical anti-malarial treatment immediately.
