Abstract:
In early January 2017, outbreaks of H5N8 highly pathogenic avian influenza (HPAI) were reported for the first time in wild and domestic birds along the shores and on some islands of Lake Victoria, in central-southern Uganda. Our whole-genome phylogenetic analyses revealed that the H5N8 viruses recovered from the outbreak in Uganda belonged to genetic clade 2.3.4.4 group-B and clustered with viruses collected in 2017 in the Democratic Republic of the Congo and in West Africa. Our results suggested that infected migratory wild birds might have played a crucial role in the introduction of HPAI H5N8 into this region.

NK cells are a crucial part of our innate immune system, acting as the first line of defense against viral infections. These cells can recognize and kill infected cells without prior exposure to the virus, effectively slowing down the spread of infection. Additionally, NK cells produce proinflammatory...
