Genomic Monitoring of H1N1, H3N2, and Influenza B Victoria Lineage Viruses in Qingyang (2020–2023): Analysis of Phylogenetic and Molecular Features of HA and NA Genes
To explore the molecular evolution and amino acid mutations of HA and NA genes in H1N1, H3N2, and B/Victoria influenza viruses in Qingyang City from 2020 to 2023, highlighting their implications for public health.
Approach:
Key Findings:
H1N1 was prevalent in 2023, H3N2 in 2020 and 2023, and B/Victoria continuously from 2020 to 2023, indicating the need for adaptive vaccine strategies.
A total of 117 samples were analyzed, revealing significant genetic variability in HA and NA genes, which may affect vaccine effectiveness.
The study highlights the need for continuous monitoring due to the rapid evolution of influenza viruses.
Interpretation:
The findings underscore the dynamic nature of influenza virus evolution, impacting vaccine efficacy and necessitating ongoing genomic surveillance to adapt public health responses.
Limitations:
Sample distribution was uneven across years and subtypes, reflecting natural epidemic characteristics and potential biases in sample selection.
The study focused only on specific influenza subtypes and may not represent all circulating strains.
Conclusion:
The research provides critical insights into the molecular evolution of influenza viruses in Qingyang, aiding in the development of targeted vaccines and antiviral strategies.
Pragmatic cluster randomized crossover study found no statistically significant difference in laboratory-confirmed influenza during the 2023-2024 season
