Abstract

We experienced a case of mixed infection with Plasmodium falciparum and P. vivax in a 48-year old Korean man. He returned to Korea from Papua New Guinea, where he worked for 20 days. Approximately one month after return to Korea, he developed high fever and myalgia. Malaria was suspected and he was admitted to our hospital. The peripheral blood smear demonstrated ring forms of P. falciparum. He was treated with quinine and doxycycline successfully. However, fever and myalgia reappeared five months later. This time, the peripheral blood smear showed gametocytes of P. vivax, while indirect immunofluorescence antibody test revealed high titers to both P. vivax and P. falciparum. He was treated with chloroquine and primaquine. Three months later, vivax malaria recurred again; he was treated with chloroquine and higher dose of primaquine. The patient was well after 6 months of follow-up. We hereby report a case of mixed malarial infections with a review of literatures.
