摘要：Background: This study aimed at estimating the incidence, mortality, burden, and geographical distribution of Crimean Congo Hemorrhagic Fever (CCHF) using Disability Adjusted Life Years (DALYs) in Iran 2009-2015. Methods: CCHF-related DALYs was calculated using a method developed by WHO for the investigation of Global Burden of Diseases (GBD). DALYs was calculated through adding years of life lost due to premature death (YLLs) to years lived with disability (YLDs). To calculate YLD, the average duration of the disease and its disability weight were set at 25 d and 0.613, respectively. The data on the incidence and mortality were collected from the CCHF surveillance system from the governmental section. Results: The highest and the lowest incidence rates of CCHF were observed in 2009 (122 cases) and 2010 (254 cases), respectively. Moreover, the lowest and highest mortality rates were reported in 2009 (20 cases) and 2012 (52 cases), respectively. The mean rate of fatality from CCHF observed between 2009 and 2015 was about 21.1%. In addition, the lowest and highest DALYs were observed in 2009 (483 cases) and 2010 (1156 cases), respectively. CCHF incidence, DALYs, and mortality rate over the studied period were higher among males than females. CCHF-related DALYs did not have an equal distribution in all provinces of Iran; some provinces were suffering from a higher burden of the disease. Conclusion: It is recommended to improve the CCHF surveillance system, identify high-risk areas, practice early diagnosis and intervention, develop vaccines, control, and fight tick, and screen livestock to control and prevent the spread of this disease.
