A Severe Case of Malaria in a 44-Year-Old Caucasian Woman on Return to Western Romania from a Visit to Nigeria.

Malaria is currently the most prevalent life-threatening infectious disease in the world. In this case report, we present a 44-year-old Caucasian woman with a low level of education and no significant past medical history who presented to the emergency room of the Emergency County Hospital of Arad, Romania, with a general affected state, a fever of 38.5 °C, chills, weakness, headache, muscle pain, nausea, icterus, and watery diarrheal stool. A viral infection was initially suspected, and the patient was transferred to the Infectious Diseases Department. The anamnesis revealed that the patient traveled to Nigeria (Ado Ekiti) and returned to Romania 14 days before presenting to the hospital without following antimalarial prophylaxis. A peripheral blood smear was conducted and revealed parasitemia with ring forms of () of 10-15% within the red blood cells. Parasitemia increased within a day to 15-18%, and her health rapidly deteriorated. She was transferred to the Victor Babeș Infectious Disease Hospital in Bucharest for the urgent initiation of antimalarial treatment. The patient's condition continued to worsen rapidly, and she succumbed to her illness due to multi-organ failure. This report details the first documented case of malaria imported from Nigeria to Romania. People traveling to malaria-endemic areas should be educated about preventing this parasitic infection, both by adopting measures to reduce the risk of mosquito bites and by using appropriate chemoprophylaxis. In the context of resuming travel after the COVID-19 pandemic, understanding and adhering to prophylactic measures is crucial to avoid tragic situations, as highlighted in this case report.
