“…Genotyping and genetic analyses revealed that the French viruses were very similar from those designated as 'Qinghai-like' sublineage viruses (Smith et al, 2006). Indeed, several characteristics were found in the French viruses identical to (Novosibirsk region, western Siberia) and Shestopalov et al, (2006) confirmed that these viruses were related to those isolated from migratory birds at Qinghai Lake described by Chen et al, (2006a), A/grebe/Novosibirsk/29/05 viruses, and A/chicken/Nigeria/641/06. These two last viruses were designated as 'Qinghai-like' virus by Smith et al, (2006).…”

“…In the months following the Qinghai lake outbreak, Qinghai-lineage H5N1 was detected in Mongolia, Inner Mongolia, Russia, and Liaoning province (North East China) in wild bird species as well as chickens (Chen et al, 2006b; Lipatov et al, 2007; Prosser et al, 2011; Shestopalov et al, 2006). Mongolia and central-eastern Siberia are vast, sparsely populated territories that contain major breeding, staging, and stopover areas for migratory waterfowl including bar-headed geese, and swan and duck species (Carboneras, 1992; Miyabayashi and Mundkur, 1999; Wetlands International, 2012).…”

The ecology of highly pathogenic avian influenza (HPAI) H5N1 has significantly changed from sporadic outbreaks in terrestrial poultry to persistent circulation in terrestrial and aquatic poultry and potentially in wild waterfowl. A novel genotype of HPAI H5N1 arose in 1996 in southern China and through ongoing mutation, reassortment, and natural selection, has diverged into distinct lineages and expanded into multiple reservoir hosts. The evolution of Goose/Guangdong-lineage highly pathogenic H5N1 viruses is ongoing: while stable interactions exist with some reservoir hosts, these viruses are continuing to evolve and adapt to others, and pose an un-calculable risk to sporadic hosts, including humans.

“…In 2005, thousands of migratory aquatic birds died in the Qinghai Lake area due to H5N1 virus infection (5,6). The H5N1 viruses of the Qinghai Lake lineage subsequently spread to Europe and Africa (7)(8)(9)(10)(11)(12)(13)(14). This wide dissemination of the Qinghai Lake H5N1 viruses exacerbated the global prevalence of avian H5N1 influenza viruses and greatly contributed to the increase in human cases of H5N1 influenza virus infection (15,16).…”

bTo gain insight into the ecology of avian influenza viruses (AIV), we conducted active influenza virus surveillance in domestic ducks on farms located on the flyway of migratory birds in the Dongting Lake region of Hunan Province, China, from winter 2011 until spring 2012. Specimens comprising 3,030 duck swab samples and 1,010 environmental samples were collected from 101 duck farms. We isolated AIV of various HA subtypes, including H3, H4, H5, H6, H9, H10, H11, and H12. We sequenced the entire coding sequences of the genomes of 28 representative isolates constituting 13 specific subtypes. When the phylogenetic relationships among these isolates were examined, we observed that extensive reassortment events had occurred. Among the 28 Dongting Lake viruses, 21 genotypes involving the six internal genes were identified. Furthermore, we identified viruses or viral genes introduced from other countries, viral gene segments of unknown origin, and a novel HA/NA combination. Our findings emphasize the importance of farmed domestic ducks in the Dongting Lake region to the genesis and evolution of AIV and highlight the need for continued surveillance of domestic ducks in this region.
