Background : Malaria has become a critical world health problem in recent years. Several factors have been responsible for increasing its incidence, such as wide usage of insecticides and drug resistance. It still remains as a matter of concern in Iran. It is under control in all parts, except in three southeastern provinces. Aim: Khorasan Razavi is one of the Iranian provinces with a lot of immigrants each year. Therefore, epidemiological study of the malaria is necessary in non-endemic provinces. Materials and Methods: This research was a descriptive study to evaluate epidemiological status of the malaria in April 2001-March 2008 using all patients' data from whole of the province. Results: Total recorded cases were 945 within 7 years. The highest incidence was observed in 2001 and the lowest in 2006. Plasmodium vivax was observed in 911 cases and 30 cases were positive for P. falciparum. Mixed species were seen in four cases. Malaria incidence had decreased since 2001. 34.6% of transmitted cases were local, 61% were transmitted from (other provinces) inside and outside the country, relapse cases formed 5.4% and transmitted routes of the rest of the cases were unknown. The highest incidence was observed in people of age 15 years and higher and mostly in men. Mashhad and Sarakhs cities had the highest incidence rate. Conclusion: Preventive efforts must be continually taken in spite of decreasing rate of the malaria.
