Distinguishing malaria from severe infection among febrile patients in emergency room is difficult, so we tried to analyze the clinical manifestations of malaria and the results of using devices as a quick way to detect malaria among febrile patients visiting an emergency medical center (EMC).
We retrospectively reviewed the clinical records of patients visiting a local EMC from January 2001 to December 2004 and confirmed as having vivax malaria by using a peripheral blood smear and Malaria antibody test (Immunochromatographic assay).
All of the 108 included patients were infected with Plasmodium vivax and suffered from high fever, but tertian fever was seen in only 41 patients (37.9%). Various symptoms included headache, myalgia, abdominal pain, and so on. Laboratory findings noted thrombocytopenia, anemia, elevated alanin aminotransferase, and coagulopathies. Malaria antibody test was used in all cases for early diagnosis in the EMC. Compared with the peripheral blood smear, malaria antibody test identified 103 cases as positive, and five cases as negative. The diagnostic sensitivity of the malaria antibody test is 95.3%.
Since south Korea is a malaria endemic area, for patients visiting an emergency room with a high fever, accompanied by thrombocytopenia and anemia, malaria must be included in the differential diagnosis whether the fever is tertian or not. The Malaria antibody test can be done by even an unskilful person, so it is a very helpful screening test and an early detection tool for malaria.
