Publication date Type Key finding PMID
2026-06-04 Molecular Adaptation Predicted PTM sites in Influenza A virus proteins exhibit host-associated evolutionary rate differences, indicating molecular adaptations related to host lineage. 42240086
2026-06 Serological Evidence Humans in Norway showed measurable post-seasonal GMT levels of influenza A(H1N1)pdm09 antibodies from 2009 to 2023, correlated with antibody prevalence in swine. 41857313
2026-06 Serological Evidence Influenza A(H1N1)pdm09 antibodies were detected in both humans and unvaccinated swine in Norway, with a significant correlation between human GMT and swine seroprevalence indicating possible interspecies transmission or shared exposure. 41857313
2026-05-25 Cross Species Transmission Phylogenetic analyses showed introductions of H1N1pdm09 from humans into pigs in Spain, generating multiple reassortant genotypes. 42244724
2026-05-25 Recombination Or Reassortment Reassortant genotypes in pigs incorporated pandemic internal cassettes and human seasonal N2 segments, indicating cross-origin genome mixing. 42244724
2026-04-07 Recombination Or Reassortment Coinfection of bovine embryonic fibroblasts with HPAI H5N1 and H1N1pdm09-like strains could enable development of reassortant influenza viruses. 41728991
2026-04 Recombination Or Reassortment The A/Swine/Jiangsu/YZ07/2024 H3N2 swine influenza virus is a complex reassortant carrying internal genes from pandemic H1N1 and possessing additional human and triple reassortant gene origins, contributing to its enhanced zoonotic potential. 41671764
2026-04 Genomic Evolution Phylogenetic and sequence analysis of H1N1 avian influenza viruses from wild birds in Shanghai showed distinct avian lineages with recombinant genetic origins diverging from mammalian H1N1 strains. 41653626
2026-04 Recombination Or Reassortment H1N1 avian influenza viruses isolated from wild birds in Shanghai exhibit complex genetic origins with frequent recombination events. 41653626
2026-04 Zoonotic Surveillance Four H1N1 avian influenza viruses were isolated from wild common teal and spot-billed ducks in Shanghai, China, as part of molecular surveillance of wild bird influenza diversity. 41653626
2026-03-21 Spillover Event Pandemic influenza A/H1N1pdm virus was detected in a European bison, suggesting possible spillover from humans. 41863702
