Seroprevalence and risk factors associated with brucellosis in humans and livestock in Nyagatare district of Rwanda.

ABSTRACT:

Brucellosis is a significant but under-reported bacterial zoonosis in Rwanda. Despite recognition as one of Rwanda's top six priority zoonotic diseases in 2019, comprehensive epidemiological data linking human and animal infections remain limited, particularly in high-risk pastoral communities.
