意大利东北部遭受了一场毁灭性的高致病性禽流感（HPAI）流行，这种流感是由 H7N1 亚型的 A 型流感病毒引起的，该病毒源自同一亚型的低致病性禽流感（LPAI）病毒的突变。 LPAI 疫情和随后的 HPAI 疫情发生在威尼托和伦巴第大区，这些地区饲养着意大利 65% 的商业家禽。高致病性禽流感疫情直接或间接导致超过1300万只禽类死亡或扑杀，不可避免地造成营销系统的混乱，给养禽业和社会带来巨大的经济损失。随着高致病性禽流感（HPAI）感染地区的数量减少和重新放养，LPAI重新出现，从而导致家禽业要求并获得接种H7亚型禽流感疫苗的选择。
North-eastern Italy has been affected by a devastating epidemic of highly pathogenic avian influenza (HPAI), caused by a type A influenza virus of the H7N1 subtype that originated from the mutation of a low-pathogenicity avian influenza (LPAI) virus of the same subtype. The LPAI epidemic and the subsequent HPAI epidemic occurred in the Veneto and Lombardia regions, which raise 65% of Italy’s commercial poultry. The HPAI epidemic resulted directly or indirectly in the death or culling of over 13 million birds, which inevitably resulted in the disruption of the marketing system and great economic losses to the poultry industry and social community. Following depopulation and restocking of the HPAI-infected areas, LPAI re-emerged, thus causing the poultry industry to demand and obtain the option to vaccinate against avian influenza of the H7 subtype.
