Risk practices for bovine tuberculosis transmission to cattle and livestock farming communities living at wildlife-livestock-human interface in northern KwaZulu Natal, South Africa

摘要

Bovine tuberculosis (bTB) is a respiratory disease of cattle that is transmitted to other animals as well as humans (zoonotic TB) through direct contact with infected animals, and consumption of contaminated food (animal products) or water. The study explains the complexities of human-animal relations, reflects on how people understand and conceptualize risk of bovine tuberculosis (bTB) in an endemic area considering the economic value of livestock keeping as well as social and cultural practices of importance to the community. The results of this study identified socio-cultural practices that involved consumption of raw or undercooked animal products and handling of infected animal products during animal slaughter as major risky practices for bTB transmission to people. Introduction of animals into a herd without bTB testing for socio-cultural purposes and sharing of resources amongst the communal herd and with wildlife were identified as risky practices for bTB transmission to cattle. The findings of this study illustrate the need for a One Health strategy that develops appropriate public health policy and related education campaigns for the community as control of zoonotic TB in people depends on the successful control of bovine TB in cattle.
