Re-Emergence of a Novel H5N1 Avian Influenza Virus Variant Subclade 2.2.1.1 in Egypt During 2014

Transboundary and Emerging Diseases, 2017
Large-scale surveillance is crucial for understanding the evolution and the emergence of avian influenza viruses (AIVs) in endemic areas. Circulation of highly pathogenic avian influenza (HPAI) subtype H5N1 is continuously causing significant economic ...

Subclade 2.2.1-Specific Human Monoclonal Antibodies That Recognize an Epitope in Antigenic Site A of Influenza A(H5) Virus HA Detected between 2015 and 2018

Viruses, 2019
Highly pathogenic avian H5 influenza viruses persist among poultry and wild birds throughout the world. They sometimes cause interspecies transmission between avian and mammalian hosts. H5 viruses possessing the HA of subclade 2.3.4.4, 2.3.2.1, 2.2.1, or

Early-Season Detection of Influenza A(H3N2) Subclade K in Wastewater, Colorado, USA, 2025–2026 [PDF]

Emerging Infectious Diseases
We assessed the value of wastewater sequencing for monitoring influenza circulation in Colorado, USA, focusing on the emergence of influenza A(H3N2) subclade K. We detected subclade K in wastewater 31 days before clinical detection.

Early influenza virus characterisation and vaccine effectiveness in England in autumn 2025, a period dominated by influenza A(H3N2) subclade K

Eurosurveillance
Influenza A(H3N2) subclade K (J.2.4.1) has dominated the 2025/26 season start in England. Post-infection ferret antisera raised against northern hemisphere 2025/26 vaccine strains showed reduced reactivity to subclade K viruses in England, aligning with ...
