A case of malaria infection in a 42-year-old woman in rural area of Mahmodabad, Mazandaran Province, North Iran was reported and discussed elaborately. She was complaining about recurrent fevers, sweating, headache and myalgia in back. After her first admission to hospital due to misdiagnose she did not receive proper treatment and the patient suffered from clinical manifestations again. Eventually in the second admission to another hospital, after a precise examination on her thick and thin blood smear the agent of disease was recognized appropriately as Plasmodium vivax and treated accordingly.
