Crimean-Congo Hemorrhagic Fever (CCHF) is a major viral zoonosis that is often fatal in humans. Controlling this disease requires knowledge of its epidemiological situation in reservoir hosts, particularly cattle. This study was conducted in a locality of the Abobo municipality following a human infection with the Crimean-Congo Hemorrhagic Fever Virus (CCHFV) from a bovine carcass, with the aim of contributing to a better understanding of CCHF epidemiology in cattle in Côte d'Ivoire. To this end, 167 bovine serum samples were collected and tested using Reverse Transcriptase Polymerase Chain Reaction (RT-PCR). The study showed the presence of CCHFV in the serum of cattle in southern Côte d'Ivoire, with six (06) animals testing positive. It also revealed that among these positive samples, 83% were from female cattle compared to 17% from males. In conclusion, this investigation highlighted, for the first time, the circulation of CCHFV in cattle serum in southern Côte d'Ivoire, indicating that precautionary measures should be taken to prevent the emergence of this disease in humans.
