　　* Avian influenza is an infectious disease of birds caused by strains of the influenza virus. The disease, which was first identified in Italy more than 100 years ago, occurs worldwide.

　　* Infection causes a wide spectrum of symptoms in birds, ranging from mild illness to a highly contagious and rapidly fatal disease resulting in severe epidemics. The latter is known as "highly pathogenic avian influenza". This form is characterized by sudden onset, severe illness, and rapid death, with a mortality that can approach 100 percent.
