Abstract

Background: Avian influenza viruses are still causing major concern not only to the poultry industry but also to human health across the globe. The live poultry markets and the small-scale local breeding of various species of birds in backyards are still playing important roles in the sustainability of most virulent influenza viruses, especially H5N8.

Methods: The authors investigated an outbreak of highly pathogenic avian influenza H5N8 in backyard flocks in Al Ahsa, Eastern Saudi Arabia that occurred in 2017-2018.

Results: A range of poultry including chickens, ostriches, ducks, pigeons and turkeys were clinically affected. Phylogenetic analysis suggested that this was a common source outbreak caused by a virus closely related to H5N8 viruses causing outbreaks elsewhere in Saudi Arabia in early 2018.

Conclusions: Small backyard flocks are still contributing to the epidemiology and transmission of H5N8.

2017-2018年沙特阿拉伯东部Al Ahsa地区后院禽群中H5N8禽流感暴发的分子特征

背景:禽流感病毒不仅对家禽业，而且对全球人类健康造成重大关切。活禽市场和在当地后院小规模饲养各种鸟类，仍然对大多数致命性流感病毒，特别是H5N8的可持续性发挥着重要作用。方法:对2017-2018年沙特阿拉伯东部Al Ahsa地区发生的高致病性禽流感H5N8疫情进行调查。结果:临床感染的禽类包括鸡、鸵鸟、鸭、鸽子和火鸡。系统发育分析表明，这是由一种与2018年初在沙特阿拉伯其他地方引发的H5N8病毒密切相关的病毒引起的共同来源疫情。结论:小型后院禽群仍是H5N8流行病学和传播的推手。
