Epidemiological Study of Brucella abortus Infection in Wasit Province

Brucellosis, caused by Brucella abortus, remains a significant public health challenge in many regions, including Wasit Province, Iraq. This study analyzed the infection's seasonal trends and age-specific prevalence to understand its epidemiology better. Data from 2022 and 2023 indicated peak IgG positivity in January, May, and June, which were in line with the seasonality of agriculture. Interestingly, IgM positivity appeared sporadically, indicating limited acute infection or a lag in diagnosis. Age group 18-41 years had higher IgG rates, which pointed to occupational risk for subjects dealing with livestock. Findings here indicate the need for targeted interventions like improved veterinary services, public awareness campaigns, and vaccination programs on the persistent risk of zoonotic transmission. Such measures would focus on lessening the burden of brucellosis and protecting human and animal health in the region.
