One Health evaluation of brucellosis control in Kazakhstan

Brucellosis is one of the main livestock disease risks in Kazakhstan. It’s been endemic there since 1930, accounting for over 1300 human cases per annum. The economic loss was 45 million USD in 2015 alone. Since 1952, Kazakhstan has implemented various control strategies with little success. One Health approaches have been suggested to tackle brucellosis, however, there is a lack of evidence for best practices to operationalise One Health in the literature, and methods for implementation are not established. The intention of this study was to introduce the One Health approach during the evaluation phase of the policy cycle. A two-day workshop was organized by the authors to familiarize participants with the evaluation methodology. Twenty-one specialists representing veterinary and public health sector, together with researchers, took part in this study. For two weeks following the workshop, first author conducted individual interviews with workshop participants to obtain individual scorings to assess knowledge integration capacity (One Health-ness). The evaluation results show that there is a lack of knowledge about the perceived damage caused by brucellosis to animal owners and other stakeholders. There is insufficient data available about farmers’ practices, interests and motivations, and also data is missing for important transmission processes such as the amount of unsafe dairy consumption. The absence of such data illustrates the extent of the uncertainty to which decision-makers are exposed despite well-elaborated transmission models and supports the importance of co-producing solutions with participatory methods. The results suggest the need for broader involvement of stakeholders. Outputs of this study could help navigate the initial stages of One Health operationalization.
