However, no mortality was reported during 2016, 2017, and 2019. The mean age of the patients was 33years± 18 SD, in males mainly (76%). Moreover, the risk groups were 29 %, 23 %, 18 % 12 %, and 6 % for butchers, animaldealers, gainers, both housewives and students and children respectively. Conclusion: Strict precautions and precise surveillance should be implemented to control the disease and protect the communityby improving the diagnosis and treatment of CCHF. The authors recommend another future study to detect the genotypingand sequencing of CCHFV in Iraq. Keywords: Crimean–Congo hemorrhagic fever; Iraq; tick.
