在爱荷华岛有3 000多万只鸟类死于禽流感,但家禽业由于生物安保能力强而基本不受影响。 Over 30 million birds dead in Iowa from bird flu, but poultry industry largely unaffected due to strong biosecurity.

自2022年以来,高致病性禽流感暴增在爱荷华岛夺走了3 000多万只鸟类的生命,最近在爱荷华岛南部猛增,对加拿大鹅和猛禽造成严重影响。 A surge in highly pathogenic avian influenza has killed over 30 million birds in Iowa since 2022, with recent spikes in southern Iowa and heavy impacts on Canada geese and raptors. 成年秃鹰表现出很强的韧性,70%的抗体检测呈阳性,表明暴露后存活,而年轻鸟类则更加脆弱。 Adult bald eagles show strong resilience, with 70% testing positive for antibodies, suggesting survival after exposure, while younger birds remain more vulnerable. 研究人员正在研究这种免疫力, Researchers are studying this immunity to inform disease control. 尽管野生鸟类感染普遍,但由于生物安保的改善,爱荷华州的家禽业在本季的影响微乎其微,只有两个地方受到影响。 Despite widespread wild bird infections, Iowa’s poultry industry has seen minimal impact this season—only two sites affected—due to improved biosecurity. 人类传播仍然罕见,仅限于与受感染的动物密切接触。 Human transmission remains rare, limited to close contact with infected animals. 官员敦促公众报告生病或死亡的鸟类并避免直接接触。 Officials urge the public to report sick or dead birds and avoid direct contact.
