The United States Centers for Disease Control and Prevention (CDC) defines public health surveillance as the ongoing, systematic collection, analysis, interpretation, and dissemination of data, including clinical signs and symptoms, laboratory test results, and prevalence of behavioral and attitudinal risk factors. Epidemiologists use these data to detect outbreaks, describe patterns of disease transmission, evaluate prevention and control programs, and prioritize future health-care needs. Traditionally, veterinary disease surveillance and monitoring programs have focused on control and eradication of diseases of agricultural significance, although significance has often been defined by the zoonotic (ability for spread between humans and animals) potential of the agent. Today, in an expanding global community, animal disease surveillance and monitoring is largely geared toward establishing national and regional disease status to support international trade in animals and animal products. Recently, diseases spread from wild animals have affected both public health and agricultural disease control programs, significantly draining valuable resources.
