Avian influenza viruses (H5N1) of clades 2.3.4.1, 2.3.4.2, and 2.3.2.1 were introduced into Laos in 2009-2010. To investigate these viruses, we conducted active surveillance of poultry during March 2010. We detected viruses throughout Laos, including several interclade reassortants and 2 subgroups of clade 2.3.4, one of which caused an outbreak in May 2010.
2009-2010 年,老挝引入了 2.3.4.1、2.3.4.2 和 2.3.2.1 分支的禽流感病毒(H5N1)。为了调查这些病毒,我们在 2010 年 3 月对家禽进行了主动监测。我们在老挝各地都检测到了病毒,包括几种跨分支重组病毒和 2.3.4 分支的两个亚群,其中一个亚群在 2010 年 5 月引发了疫情。
