Factors Associated with the Prevalence of Bovine Tuberculosis in the Kafue Basin of Zambia

Abstract

Worldwide, bovine tuberculosis is most common in agricultural regions of Central and South America, Sub-Saharan Africa and South-Western Asia. Bovine tuberculosis was reported to be endemic in the Zambian traditional cattle sector with a high herd prevalence of 49.8% recorded from areas within, and adjacent to the Kafue Basin as far back as 1995. An analytical cross sectional study design was applied to a sample size of 384 selected cattle owners in the Kafue Basin. A semi-structured questionnaire was administered to the cattle owners who were randomly selected. The data was analyzed using STATA Version 15 Software. The results from the study showed that 54% of the cattle owners experienced bovine tuberculosis among their cattle while 46% did not experience bovine tuberculosis. The prevalence of bovine tuberculosis in cattle was higher among the male cattle owners (76%) compared to female cattle owners (24%). There was a significant relationship of p value < 0.029 between level of knowledge of cattle owners and the prevalence of bovine tuberculosis. Unemployed cattle owners had higher odds of experiencing bovine tuberculosis among their cattle (OR 3.488; 95% CI 1.341-9.067) and the relationship was statistically significant at p value < 0.010. There was equally a significant relationship of p value < 0.042 between vaccination status of animals and the occurrence of bovine tuberculosis. The study showed that the majority of cattle owners lacked awareness and had a lower level of understanding of the disease and its public health significance. Therefore, the implications of the study suggest the creation of disease control programs that will ensure regular herd testing for bovine tuberculosis, routine vaccinations of animals, deliberate quarantine of infected animals as well as community health education about transmission, control and prevention of the disease.
