Risk-Based Disease Surveillance: A Manual for Veterinarians on the Design and Analysis of Surveillance for Demonstration of Freedom from Disease [open pdf - 0B]
"The international movement of animals and animal products has been made cheaper and faster through improved transport infrastructure. Increasing human and livestock population has placed pressure on wildlife habitats, resulting in closer contact between wildlife, domestic animal populations and humans. This complex mix of factors means that 'traditional' livestock diseases have the opportunity to spread and multiply much more quickly, and that 'new' diseases, arising from wildlife populations or genetic changes in existing pathogens, have a much greater chance to impact on animal and human populations. Managing these disease threats poses enormous challenges and requires inputs from many disciplines. Good quality information is one essential requirement: what diseases exist; where they are found; what impact they are having; which populations are at risk; how we can prevent, control or eradicate these diseases. Animal disease surveillance plays a central role in providing this information. [...] This manual seeks to present a comprehensive overview of the issues relating to risk-based surveillance for the purpose of demonstrating freedom from disease. It is targeted at veterinarians who are interested in surveillance and the analysis of surveillance data. [...] It also aims to be relevant to the animal health situation in developing countries, as well as more developed countries."
