Emergence of seasonal influenza A(H3N2) variants with immune escape potential warrants enhanced molecular and epidemiological surveillance for the 2025-2026 season.

Journal of the Association of Medical Microbiology and Infectious Disease Canada = Journal officiel de l'Association pour la microbiologie medicale et l'infectiologie Canada
Background All of the major antigenic changes in influenza A(H3N2) viruses since 1968 have involved mutations at just nine amino acid positions, called cluster transition sites, surrounding the receptor binding region of the hemagglutinin surface protein.

Molecular Epidemiology of Influenza A(H3N2) Virus Reinfections [PDF]

The Journal of Infectious Diseases, 2002
Between 1979 and 1989, families enrolled in the Houston Family Study were prospectively monitored for influenza virus infections. Reinfection with the H3N2 subtype occurred in a number of family members, and 6 pairs of isolates (interval between collection of first and second isolate, 2-5 years) were available for molecular analysis.

Extended influenza seasons in Australia and New Zealand in 2025 due to the emergence of influenza A(H3N2) subclade K viruses

Euro surveillance : bulletin Europeen sur les maladies transmissibles = European communicable disease bulletin
In Australia and New Zealand, late outbreaks of an A(H3N2) variant virus termed subclade K extended the 2025 influenza season. Subclade K viruses were genetically and antigenically distinct from the 2025 vaccine A(H3N2) strain A/Croatia/10136RV/2023 ...

Major antigenic site B of human influenza H3N2 viruses has an evolving local fitness landscape

Nature Communications, 2020
Antigenic drift of influenza virus hemagglutinin (HA) is enabled by facile evolvability. However, HA antigenic site B, which has become immunodominant in recent human H3N2 influenza viruses, is also evolutionarily constrained by its involvement in ...

Antigenic Distance between North American Swine and Human Seasonal H3N2 Influenza A Viruses as an Indication of Zoonotic Risk to Humans

Journal of Virology, 2021
Human H3N2 influenza A viruses spread to pigs in North America in the 1990s and more recently in the 2010s. These cross-species events led to sustained circulation and increased H3N2 diversity in pig populations.

A Clinicoradiological Profile of H3N2 Outbreak in Western India

Journal of Marine Medical Society
Introduction: Although H3N2 outbreaks were once rare, they have become more common in recent years. With a significant toll on health-care resources and the ability to cripple any society, the epidemiological significance of this disease is paramount ...

Changes in the Nasal Microbiota of Pigs Following Single or Co-Infection with Porcine Reproductive and Respiratory Syndrome and Swine Influenza A Viruses

Pathogens, 2021
Host-microbiota interactions are important in shaping immune responses that have the potential to influence the outcome of pathogen infection. However, most studies have focused on the gut microbiota and its possible association with disease outcome ...
