چکیده

Influenza A viruses can be divided into two groups on the basis of their ability to cause disease and death in poultry. The very virulent viruses cause highly pathogenic avian influenza [HPAI], with flock mortality as high as 100% in chickens and other susceptible poultry. These viruses have been restricted to subtypes H5 and H7, although not all H5 and H7 viruses cause HPAI. All other viruses cause a milder, primarily respiratory, disease [LPAI], unless exacerbated.
