Growth in the livestock sector is associated with heightened risk for epidemic diseases. The
increasing spillover of new diseases from wildlife is being driven by wide-scale anthropogenic
changes allowing for more frequent and closer wildlife-human and wildlife-livestock contacts.
Increasing epidemics in livestock are associated with rapid transition of livestock systems from
extensive to intensive, and local to global movement of livestock and their products through
value chain networks with weak biosecurity. Major livestock epidemics in the past two decades
have had substantial economic impacts, and the COVID-19 pandemic highlights the devastating
socio-economic consequences that spillovers can have when not identified and controlled early
in the process of emergence. This highlights the importance of Veterinary Services to integrated,
whole-of-society efforts to control infectious diseases in animals. Emphasis within Veterinary
Services must be placed on prevention and preparedness. We suggest four areas for continued
improvement in Veterinary Services to meet this challenge. These include continued
development of staff capacity for risk assessment and value chain analysis linked to improved
policies and communication, appropriate adaptation of approaches to prevention and control in
resource-poor settings, improved multi-sectoral and transboundary cooperation allowing for
shared resources and expertise, and systematic approaches that enable Veterinary Services to
influence decision-making for trade, markets, business, public health, and livelihoods
development at the national and regional levels.
