Camel brucellosis is an infectious and zoonotic diseases caused by Brucella abortus and Brucella melitensis. A cross-sectional study was conducted on 450 camels from December, 2020 until August, 2021 with the aim of determining sero-prevalence and assessing the associated risk factors for camel brucellosis and its public health significances from purposively selected three districts namely (Fik, Hamaro and Laghida) of Erer zone, Somali Regional state, based on distribution of camel population and sampled using systematic random sampling. The overall sero-prevalence of Brucella in Erer zone was 4.8% (95%, CI: 2.8-6.8). However, the Seroprevalence varied among the different districts with Lagehida 10% (95%, CI: 1.7-18.7), followed by Fik 5.7% (95%, CI: 0.9-10.5) and Hamaro 1.9% (95%, CI: 0.007-0.0522). By computing univariate logistic regression analysis risk factors such as; sex, age, districts, parity, herd sizes, camels that co-exist with other ruminants and reproductive disorder (abortion) (p<0.05) were statistically significant as major risk factor for transmission of camel brucellosis. Furthermore, multivariable logistic regression analysis of the risk factors revealed that the age, herd size and camels that are kept closely together with other ruminants with adjusted odds ratio (OR) of 3.3 (95%, CI: 1.58-6.74), 4.6 (95%, CI: 2.66-8.10) and 11.4 (95%, CI: 1.39-85.46), respectively were the major risk factors for the occurrence of camel brucellosis. Moreover, the questionnaire survey found common practices like lack of awareness about zoonotic diseases, raw milk consumption, and close contact with animals in pastoral communities. This highlights the need for further advanced epidemiological studies, herd health prevention, control strategies, and public health education to reduce brucellosis risk in both animals and pastoral communities.
