H10 subtype avian influenza viruses (AIVs) have been isolated from wild and domestic avian species worldwide and have occasionally crossed the species barrier to mammalian hosts. Fatal human cases of H10N8 infections and the recent detection of human H10N3 infections have drawn widespread public attention. In this study, 25 H10Nx viruses were isolated from wild waterfowl in China during a long-term surveillance of AIVs.

- In October 2020, 13 cases of a highly pathogenic strain of avian influenza A(H5N8) were found in wild ducks in Ningxia, China.
- These identified viruses were similar to H5N8 strains that were primarily present in European poultry earlier that year.
- Researchers also tracked the movement of the infected wild ducks and gathered evidence showing how the virus was spreading.
Article Synopsis
- Researchers isolated highly pathogenic avian influenza viruses H5N8 and H5N1 from migratory birds and fecal samples in Tibet, China, in May 2021.
- Phylogenetic analyses suggest the viruses may have spread from migratory birds' wintering grounds in South Asia, highlighting the complex interactions between different viral populations.
- The study emphasizes the need for increased surveillance of avian influenza in these regions and calls for stronger international collaboration to address potential outbreaks.

Article Synopsis
- Highly pathogenic influenza A(H5N8) viruses pose a serious public health threat as they can infect humans and have caused multiple outbreaks in birds globally.
- Following the detection of H5N8 in swans in Inner Mongolia, researchers monitored swan migration routes in central China and isolated 42 avian influenza viruses, predominantly H5N8.
- Phylogenetic and phylogeographic analyses revealed that H5N8 viruses from swans in central China share a common evolutionary source, with one sub-clade likely originating from Russian poultry, indicating swans' role in the virus's spread.
