Objective: Brucellosis is a zoonotic disease usually acquired through direct contact with the infected animals and consumption of contaminated milk and meat products. In humans Brucellosis presents similar signs with other febrile diseases like Malaria, typhoid and other febrile conditions. This study was carried out to determine the prevalence of Brucella abortus among patients with fever but were negative for Malaria.
Results: A cross-sectional study was carried out in Namayumba Health Centre IV, Wakiso district involving 200 participants. Blood samples was screened for B. abortus using Serum Agglutination Test and confirmed with Tube Agglutination test. A questionnaire was used to collect data on socio-demographic characteristics and human Brucellosis related risk factors. Human B. abortus sero-prevalence was at 7.5% (n = 200). The prevalence was high among participants aged 18-35 years (13.3%), muslims 12 (14.0%), those with no formal education (33.3%) and divorced 2 (14.3%). Consuming of raw milk (OR 2.162, 95% CI 0.021-1.379) and being a Muslim (OR 6.101, 95% CI 1.601-23.248) were associated with increased risk of Brucella abortus. It was concluded that human Brucella infection due to Brucella abortus is commonly associated with consumers of raw milk products and muslims in Wakiso district.
