Introduction - Biological threat reduction
Abstract:
Animal diseases, including zoonoses, have the potential to negatively impact economies, the environment, society and public health. It is currently thought that over 60% of human diseases and over 80% of agents that can be used for bioterrorism are of animal origin. The emergence and spread of animal diseases, including zoonoses, is at an all-time high. This increase in disease emergence and spread is thought to be the result of an increase in intensive farming, global travel, human pressure on ecosystems and social unrest. As new diseases and/or strains emerge, they travel freely and do not respect political borders.
