Malaria caused by Plasmodium species is characterized by paroxysms of fever, chills, fatigue, anemia, and splenomegaly. Vivax malaria has lately re-emerged as an infectious disease and has exhibited high transmission rate in northern Gyeonggi-do province. We encountered a case of malaria in a child presenting with fever and thrombocytopenia who had recently made a school excursion to Pocheon-gun, Gyeonggi-do. The child was diagnosed with Plasmodium vivax malaria and treated with hydroxychloroquine and primaquine. Here, we present this case with a brief review of the literature.
