2006年至2009年期间发生的事件被持续的H5 N1（高致病性应报告禽流感[HPNAI]）泛动物传染病所掩盖，在审查期间，H5 N1感染了三大洲（非洲、亚洲和欧洲）的63个国家。印度尼西亚和埃及这两个国家已正式向世界动物卫生组织宣布该疾病为地方病，而其他国家则采用了各种旨在遏制、控制和根除的方法。这些方法取得了不同程度的成功，但在2009年，几个先前宣布自己没有HPNAI的国家再次受到感染。此外，即使当地没有家禽暴发，也继续在野鸟种群中广泛检测到该病毒。南非（2006年鸵鸟感染H5 N2）和英国也报告了其他家禽HPNAI疫情。(in 2008年H7 N7禽流感疫情）。同样值得注意的是2007年在北非野生鸟类种群中发现H5 N2 HPNAI的报告。改善对家禽中应报告的禽流感（NAI）的主动监测系统和警惕，特别是在感染后的临床症状可能不明显的宿主群中（例如，家禽），不可避免地导致发现和报告其他活动。从比利时家禽中分离/检测到低致病性NAI H5或H7病毒（H5 N2，2008），中国台北（H5 N2，2008年），丹麦（H5 N2，2006; H7 N1，2008），法国（H5 N2，2007），德国（H7 N3，2008），意大利（H7 N7，2006; H7 N3，2007-08）、荷兰（H7 N7，2006）、葡萄牙（H5 N2，2007; H5 N3，2007）、大韩民国（H7 N8，2007; H5 N2，2008）和英国(H7N3，2006; H7N2，2007）。此外，H6和H9病毒在家禽种群中也有显著的活动，特别是在亚洲。
Events during the period extending from 2006 to 2009 have been overshadowed by the ongoing panzootic with H5N1 (highly pathogenic notifiable avian influenza [HPNAI]), which has afflicted 63 countries anti three continents (Africa, Asia, and Europe) during the review period. Two countries, Indonesia and Egypt, have formally declared the disease endemic to the World Organisation for Animal Health, while others have used a variety of approaches aimed at containment, control, and eradication. These approaches have achieved variable success, but in 2009 several countries that had previously declared themselves free of HPNAI became reinfected. In addition, the virus continued to be detected widely in wild bird populations, even in the absence of local poultry outbreaks. Other poultry outbreaks with HPNAI have been reported in South Africa (in ostriches with H5N2 in 2006) and the U.K. (in chickens with H7N7 in 2008). Also notable was the report of H5N2 HPNAI in wild bird populations in North Africa in 2007. Improved active surveillance systems and vigilance for notifiable avian influenza (NAI) in domestic poultry, especially in host groupings, in which clinical signs following infection may be inapparent (e.g., domestic waterfowl), have inevitably resulted in the detection and reporting of other activity. Low pathogenicity NAI H5 or H7 viruses were isolated/detected from poultry in Belgium (H5N2, 2008), Chinese Taipei (H5N2, 2008), Denmark (H5N2, 2006; H7N1, 2008), France (H5N2, 2007), Germany (H7N3, 2008), Italy (H7N7, 2006; H7N3, 2007-08), the Netherlands (H7N7, 2006), Portugal (H5N2, 2007; H5N3, 2007), the Republic of Korea (H7N8, 2007; H5N2, 2008), and the U.K. (H7N3, 2006; H7N2, 2007). In addition, there has also been significant activity with H6 and H9 viruses in poultry populations, especially in Asia.
