Evolution of H3 avian influenza virus in China: Implications for pandemic preparedness AvianInfluenza BirdFlu Evolution Influenza Pandemic Virus Virology CDC_NCEZID
By Dr. Sanchari Sinha Dutta, Ph.D.Apr 18 2023Reviewed by Danielle Ellis, B.Sc. A study published in the journal Emerging Infectious Diseases provides a comprehensive overview of the evolution of H3 avian influenza viruses in China.
The first human case of AIV infection was detected in China in April 2022. The patient was present with recurrent fever and severe pneumonia. The second case with mild influenza symptoms was detected in May 2022. These cases raised global concern about the possibility of a significant public health threat by H3N8 AIVs.
Spatial and temporal distribution of avian influenza virus subtype H3 isolated from poultry-associated environments, China, 2009–2022. A) Spatial distribution of environmental H3 subtype viruses. One H3 isolate without neuraminidase subtype was designated as H3Nx. Provinces where human infections with H3N8 were reported are noted. B) Number of environmental H3 subtype isolates per year. This figure includes all H3 isolates sequenced by the Chinese National Influenza Center.
They further classified the phylogenetic trees into divergent lineages or sublineages. Furthermore, they estimated the time to the most recent common ancestor of human H3N8 viruses. The phylogenetic analysis revealed an intense genetic exchange between H3 AIVs, leading to the generation of multiple genotypes. A total of 126 genotypes were identified from 284 H3 AIVs during 2009 – 2022. Further analysis revealed that 73 genotypes emerged from 212 H3N2 genomes, 11 genotypes from 14 H3N3, 17 genotypes from 25 H3N6, and 25 genotypes from 33 H3N8.
