PLoS ONE, 2007 Despite a mass of research on the epidemiology of seasonal influenza, overall patterns of infection have not been fully described on broad geographic scales and for specific types and subtypes of the influenza virus.

Swine-to-Human Transmission of Influenza A(H3N2) Virus at Agricultural Fairs, Ohio, USA, 2012
Emerging Infectious Diseases, 2014 Agricultural fairs provide an opportunity for bidirectional transmission of influenza A viruses. We sought to determine influenza A virus activity among swine at fairs in the United States.

Infections with Influenza A/H3N2/ Subtype in Poland in the 2016/2017 Epidemic Season. [PDF]
Adv Exp Med Biol, 2018 The 2016/2017 epidemic season was characterized by a lower number of diagnostically tested samples of the nasal and throat swabs and bronchoalveolar lavage fluid, compared with the preceding season. The predominant influenza subtype found was A/H3N2/ which was notably diagnosed in patients over 25 years of age.

Adjuvanted Influenza Vaccines Elicits Higher Antibody Responses against the A(H3N2) Subtype than Non-Adjuvanted Vaccines. [PDF]
Vaccines (Basel), 2020 Background: vaccination is the best approach to prevent influenza infections so far. Serological studies on the effect of different vaccine types are important to address vaccination campaigns and protect our population.

Recurring Temporal Association Between Influenza A Epidemics and Subsequent Influenza B Dominance in Post-Pandemic Korea, 2022-2026. [PDF]
J Med VirolABSTRACT Post‐pandemic influenza dynamics have shown unusual patterns globally. We investigated the re‐emergence and recurrent seasonal dominance of influenza B in Korea across three post‐pandemic seasons (2022−2026). We analyzed 157 consecutive weeks of national sentinel surveillance data (K‐SenS, Korea Disease Control and Prevention Agency), covering

Genomic and Clinical Analysis of Influenza A in Hospitalized Adults, 2019-2024: Exploratory Evidence on Neuraminidase and Polymerase Acidic Protein Mutation-Outcome Associations From a Single Center. [PDF]
Influenza Other Respir VirusesABSTRACT Background Antivirals are widely used to treat influenza, but potential resistance mutations remain a major challenge, and clinical data on key resistance mutations are limited. Methods We conducted a retrospective cohort study of 765 adults with RT‐PCR‐confirmed influenza A admitted to Ruijin Hospital, Shanghai, between 2019 and 2024 to ...

The Journal of Molecular Diagnostics, 2010 Influenza virus subtyping has emerged as a critical tool in the diagnosis of influenza. Antiviral resistance is present in the majority of seasonal H1N1 influenza A infections, with association of viral strain type and antiviral resistance. Influenza A virus subtypes can be reliably distinguished by examining conserved sequences in the matrix protein ...

Temporal Shifting of Influenza Subtype Dynamics in Pakistan Following the COVID-19 Pandemic: A 10-Year FluNet Analysis, 2015-2024. [PDF]
Influenza Other Respir VirusesABSTRACT Background The COVID‐19 pandemic and associated nonpharmaceutical interventions caused unprecedented suppression of influenza circulation globally. Pakistan, with its high population density and evolving surveillance capacity, lacks long‐term data on post‐COVID‐19 influenza patterns, essential for guiding vaccine policy.

Frequency of influenza H3N2 intra-subtype reassortment: attributes and implications of reassortant spread [PDF]
BMC Biology, 2016 De plus en plus de preuves suggèrent que le réassortiment de la grippe contribue non seulement à l'émergence de nouvelles pandémies humaines, mais joue également un rôle important dans les épidémies de grippe saisonnière, la gravité de la maladie, l'évolution et l'efficacité des vaccins.

Human microRNAs profiling in response to influenza A viruses (subtypes pH1N1, H3N2, and H5N1) [PDF]
Experimental Biology and Medicine, 2015 MicroRNAs (miRNAs) play an important role in regulation of gene silencing and are involved in many cellular processes including inhibition of infected viral replication. This study investigated cellular miRNA expression profiles operating in response to influenza virus in early stage of infection which might be useful for understanding and control of ...
