Avian influenza biosecurity: a key for animal and human protection.

Modern biosecurity methods have provided the best way of preventing the spread of a communicable disease since people realised that human and animal contact can transmit exotic diseases. The avian influenza virus is readily transmitted through animal vectors and inanimate matter and incurs heavy losses to the poultry industry. Biosecurity measures include the prevention of vaccination of flocks in an endemic area and the isolation of farms from the surrounding world (villages, other farms, fields, etc.). Veterinary services work in liaison with owners to implement national quarantine and vaccination measures for the benefit of farmers and the industry and for protection of public health.
