Risk factors for human brucellosis among a pastoralist community in South-West Kenya, 2015.

Forty-three cases and 86 controls were recruited from a population of 4792 individuals in 801 households. The mean age for the cases was 48.7 years while that of the controls was 37.6 years. The dominant gender for both cases (62.7%) and controls (58.1%) groups was female. Regular consumption of un-boiled raw milk and assisting animals in delivery were significantly associated with brucellosis by OR 7.7 (95% CI 1.5-40.1) and OR 3.7 (95% CI 1.1-13.5), respectively.
