Abstract

Purpose of review: This review aims to discuss the current state of human infections with Avian Influenza A (H5) and (H9) viruses, to support awareness of the global epidemiology among clinicians and public health professionals interested in emerging respiratory infections.

Recent findings: Among increasing numbers of detections in avian species of Avian Influenza A(H5N1) clade 2.3.4.4b globally, reported human cases of severe infection have been rare.Enhanced surveillance of persons exposed to avian species infected with Influenza A (H5N1) clade 2.3.4.4b in different countries has identified small numbers of asymptomatic individuals with Avian Influenza A (H5N1) detected by PCR from the upper respiratory tract; some of these instances have been considered to represent contamination rather than infection.There have also been recent sporadic human cases of Avian Influenza A(H9N2) internationally, including in China and Cambodia.

Summary: Human infections with Avian Influenza A(H5) and (H9) viruses remain of interest as an emerging infection both to clinicians and public health professionals. While maintaining effective surveillance is essential, one health strategies to control infection in avian species will be key to mitigating these risks.

H5 和 H9 禽流感--对人类的潜在再发动物传染病威胁。

综述的目的：本综述旨在讨论人类感染甲型禽流感（H5）和（H9）病毒的现状，以帮助对新出现的呼吸道感染感兴趣的临床医生和公共卫生专业人员了解全球流行病学：在全球越来越多的禽类中检测到甲型 H5N1 流感 2.3.4.4b 支系，但报告的人类严重感染病例却很少。3.4.4b 在不同国家发现了少量上呼吸道 PCR 检测出的无症状甲型 H5N1 禽流感患者；其中一些病例被认为是污染而非感染。摘要：人感染甲型禽流感（H5）和（H9）病毒作为一种新出现的传染病，仍然受到临床医生和公共卫生专业人员的关注。虽然保持有效的监测至关重要，但控制禽类感染的卫生策略将是降低这些风险的关键。
