BACKGROUND: Crimean-Congo hemorrhagic fever (CCHF) is a highly fatal, tick-borne zoonosis in humans for which no licensed vaccines exist. Camels are important hosts of Hyalomma ticks, yet data on their role in CCHF epidemiology in Nigeria are limited. This study assessed seroprevalence and risk factors of the CCHF virus (CCHFV) in camels from major livestock markets in northern Nigeria. MATERIALS AND METHODS: < 0.05). RESULTS: CCHFV antibodies were detected in 89.4% of camels (95% CI: 87.1-91.4%). Prevalence was highest in Maiduguri (94.2%), followed by Maigatari (92.0%) and Illela (80.4%). Females (94.1%) had higher seropositivity than males (84.9%), and adults (>48 months) exceeded younger camels (94.3% vs. 81.7%). Tick infestation was strongly associated with seropositivity. Multivariable analysis showed younger age (OR = 0.35, 95% confidence intervals [CI]: 0.19-0.66), male sex (OR = 0.33, 95% CI: 0.18-0.60), and absence of ticks (OR = 0.45, 95% CI: 0.26-0.81) were significantly linked to reduced odds of seropositivity. CONCLUSION: The very high seroprevalence observed in camels suggests that they may contribute to the epidemiology of CCHF in northern Nigeria. Although cultural practices such as consumption of raw camel milk and urine are common, their role in CCHFV transmission remains uncertain; therefore, further studies are recommended to investigate their potential epidemiological significance. Strengthening One Health-based surveillance, vector control, and public education is critical to reducing zoonotic transmission and protecting human and animal health.
