H7N1 is low-pathogenic avian influenza which can result in huge economic losses to the poultry industry and pose a serious threat to human health. Between 1999 and 2000, a H7N1 virus outbreak in Italy resulted in the death of more than 13 million chickens and caused extensive economic losses.
H7N1 AIVs are circulating widely in many areas, including North America, Europe, southern China, New Zealand and Australia. A previous study also found that an H7N1 AIV with no history of human infection could obtain capacity of airborne transmission among ferrets introduced by serial passage test.
