Phylogenetic Divergence and Molecular Signatures of Porcine Epidemic Diarrhea Virus S‐INDEL Subtype
Porcine epidemic diarrhea virus (PEDV) continues to evolve under the selective pressures of vaccine‐induced immunity and environmental factors, leading to immune evasion and sustained piglet mortality. In this study, we characterized PEDV field strains collected across China from 2023 to 2026 and observed substantial g...
