Immunoprophylaxis in Biosecurity Programs

摘要

During the last decade, the term biosecurity has been used frequently to describe measures for prevention and control of diseases (FAO 2011, OIE 2011). However, biosecurity remains a term without broad acceptance in the international community. Biosecurity is used in human as well as veterinary medicine, including in relation to bioterrorism. Biosecurity has even been used when communicating about prevention of harmful environmental consequences associated with the spread of diseases and other invasive alien species.A commonly used definition of biosecurity in veterinary medicine refers to a set of measures that reduces the risk of introduction and spread of disease agents. Biosecurity can be applied to different population levels: from the farm to the region to thenational level. Biosecurity measures are used to prevent the entry of infectious agents into an animal population, called external biosecurity or bioexclusion. However, the prevention of spread and control of pathogens within a population, called internal biosecurity or biocontainment, is also an important part of biosecurity.
