“…There is good agreement with the previous studies of the sporadic US sequences but the results are less clear for the recent Eurasian outbreak and its sub-sequent spread to North America (16,26). Sequences from that outbreak have been classified into two groups based on the hemagglutinin gene segment, Gochang and Buan (25). The Gochang sequences also form a cluster with the sequences from China and this is the suggested point of origin.…”

The hemagglutinin subtypes from Influenza A can be divided into distinct lineages. This is important for tracing the evolutionary history of the gene. It allows regional lineages to be identified and studied. The process of lineage identification depends on phylogenetic analysis to identify the distinct clades within the data.Identification of lineages within the Influenza Internal genes would help to simplify the analysis of reassortment where these genes are transferred between subtypes. In this paper we show that a rapid clustering method can be used to assign lineages to the internal gene segments without the need for a full phylogenetic analysis.

“…In January 2014, HPAI H5N8 viruses were detected in South Korea, where they infected birds of 161 poultry farms and resulted in the culling of 14 million poultry by September 2014 [8]. In April 2014, HPAI H5N8 virus was detected on a chicken farm in Japan.…”

Wild bird surveillance around outbreaks of highly pathogenic avian influenza A(H5N8) virus in the Netherlands, 2014, within the context of global flyways

Highly pathogenic avian influenza (HPAI) A(H5N8) viruses that emerged in poultry in east Asia since 2010 spread to Europe and North America by late 2014. Despite detections in migrating birds, the role of free-living wild birds in the global dispersal of H5N8 virus is unclear. Here, wild bird sampling activities in response to the H5N8 virus outbreaks in poultry in the Netherlands are summarised along with a review on ring recoveries. HPAI H5N8 virus was detected exclusively in two samples from ducks of the Eurasian wigeon species, among 4,018 birds sampled within a three months period from mid-November 2014. The H5N8 viruses isolated from wild birds in the Netherlands were genetically closely related to and had the same gene constellation as H5N8 viruses detected elsewhere in Europe, in Asia and in North America, suggesting a common origin. Ring recoveries of migratory duck species from which H5N8 viruses have been isolated overall provide evidence for indirect migratory connections between East Asia and Western Europe and between East Asia and North America. This study is useful for better understanding the role of wild birds in the global epidemiology of H5N8 viruses. The need for sampling large numbers of wild birds for the detection of H5N8 virus and H5N8-virus-specific antibodies in a variety of species globally is highlighted, with specific emphasis in north-eastern Europe, Russia and northern China.

“…Thereafter, these viruses have been circulating in both avian populations in South Korea [3,4] and sporadically in neighbouring countries, including China and Japan. Since November 2014, H5N8 HPAIVs have also appeared in poultry and wild birds in Europe [5,6].…”

Genetic diversity of highly pathogenic H5N8 avian influenza viruses at a single overwintering site of migratory birds in Japan, 2014/15

We isolated eight highly pathogenic H5N8 avian influenza viruses (H5N8 HPAIVs) in the 2014/15 winter season at an overwintering site of migratory birds in Japan. Genetic analyses revealed that these isolates were divided into three groups, indicating the co-circulation of three genetic groups of H5N8 HPAIV among these migratory birds. These results also imply the possibility of global redistribution of the H5N8 HPAIVs via the migration of these birds next winter.
