Four avian influenza viruses have been recognized that have genetic coding for highly pathogenic avian influenza viruses, but do not show virulence for chickens. The two different mechanisms that prevent this potential being expressed have been determined for A/chicken/Pennsylvania/1/83 (H5N2) and A/goose/Guandong/2/96 (H5N1), but neither of these applies to A/turkey/England/87-92BFC/91 (H5N1) or A/chicken/Texas/298313/04 (H5N2).
已经识别出四种禽流感病毒，它们具有高致病性禽流感病毒的基因编码，但对鸡不显示毒力。对于A/鸡/宾夕法尼亚/1/83（H5N2）和A/鹅/广东/2/96（H5N1），已经确定了两种阻止这种潜在毒力表达的不同机制，但这两种机制都不适用于A/火鸡/英格兰/87 - 92BFC/91（H5N1）或A/鸡/德克萨斯/298313/04（H5N2）。
