Antiviral Resistance Associated With Multiple Mutations Occurring in Seasonal Influenza A(H3N2) Virus in a Patient Treated With Oseltamivir. [PDF]

Clin Case Rep
ABSTRACT Our case highlights the importance of early diagnosis in respiratory illness and timely detection of drug resistance so that antiviral treatment can be initiated and modified, particularly for high‐risk groups. Vaccination and early, carefully dosed antiviral treatment are key to mitigating severe influenza cases, especially in ...

Human-Origin Influenza A(H3N2) Viruses Revealed in Swine Farms During the Period 2022–2025 in Kazakhstan [PDF]

Animals
Seasonal human influenza A viruses (H1N1 and H3N2) are frequently transmitted to swine populations. Continued transmission of these viruses among swine results in genetic and phenotypic changes, creating new lineages of swine influenza viruses that ...

Assessment of pre and postinfection immunity to the hemagglutinin proteins of Influenza A(H1N1)pdm09 and Influenza A(H3N2) in India: a retrospective longitudinal study [PDF]

Virology Journal
Background Hemagglutinin (HA), one of the main surface glycoproteins of the influenza virus, is essential for viral entry into host cells. Antibodies targeting HA can neutralize the virus, offering protection against infection.

Northern Hemisphere 2025/26 influenza vaccine effectiveness during months with influenza A(H3N2) subclade K predominance— Suzhou, Eastern China [PDF]

International Journal of Infectious Diseases
During this 2025/26 Northern Hemisphere influenza season, the predominant influenza A(H3N2) subclade K virus has binding site mutations and postvaccine sera reduced inhibition, raising concerns about antigenic differences with available vaccines.

Prior immunity to seasonal influenza A(H3N2) virus confers varying levels of cross-protection against challenge with clade 2.3.4.4b A(H5N1), A(H7N9), or A(H9N2) virus in a ferret model [PDF]

Microbiology Spectrum
Evaluating how prior immunity to seasonal influenza viruses influences subsequent zoonotic influenza A virus (IAV) infection in animal models is critical for pandemic preparedness.
