One of the most important infectious diseases in the world is Malaria. About half of the world populations are exposed to the risk of the disease. The program for controlling and eradication of Malaria has been being conducted in our country since many years ago. One of the public health problems in the endemic and non-endemic countries is Imported Malaria which can cause new and permanent infected foci. Population movement and travelling from endemic areas can transmit the disease to the clean areas and can also transmit the drug resistant Protozoa particularly Plasmodium Falciparum. Our case study describes a ۳۰ year old person who has travelled to India for one month. He has visited a doctor in India because of fever, chills, malaise, and has received symptomatic treatment without any specific diagnosis .After returning to Iran, the symptoms appeared again after visiting by a doctor he has hospitalized with a diagnosis of Fever of unknown origin (FUO).He was checked for three days and on the fourth day, the blood smear of the patient showed Plasmodium Vivax. Ultimately he received the appropriate treatment and was discharged from the hospital in a good condition.
