Evolution, recombination and geographic spreading of global Coxsackievirus A6
Background
The increasing incidence of hand, foot, and mouth disease (HFMD) associated with Coxsackievirus A6 (CVA6) has become a very significant public health problem. The aim of this study is to investigate the recombination, geographic transmission, and evolutionary characteristics of the global CVA6.
Methods
From 2019 to 2022, 73 full-length CVA6 sequences were obtained from HFMD patients in China and analyzed in combination with 1032 published whole genome sequences. Based on this dataset, the phylogenetic features, recombinant diversity, Bayesian phylodynamic characteristics, and key amino acid variations in CVA6 were analyzed.
Results
The four genotypes of CVA6, A, D, E, and F, are divided into 24 recombinant forms (RFs, RF-A – RF-X) based on differences in the P3 coding region. The eastern China region plays a key role in the dissemination of CVA6 in China. VP1–137 and VP1–138 are located in the DE loop on the surface of the CVA6 VP1 protein, with the former being a highly variable site and the latter having more non-synonymous substitutions.
Conclusions
Based on whole genome sequences, this study contributes to the CVA6 monitoring, early warning, and the pathogenic mechanism by studying recombination diversity, geographical transmission characteristics, and the variation of important amino acid sites.
期刊介绍：
The Journal of Clinical Virology, an esteemed international publication, serves as the official journal for both the Pan American Society for Clinical Virology and The European Society for Clinical Virology. Dedicated to advancing the understanding of human virology in clinical settings, the Journal of Clinical Virology focuses on disseminating research papers and reviews pertaining to the clinical aspects of virology. Its scope encompasses articles discussing diagnostic methodologies and virus-induced clinical conditions, with an emphasis on practicality and relevance to clinical practice.
The journal publishes on topics that include:
• new diagnostic technologies
• nucleic acid amplification and serologic testing
• targeted and metagenomic next-generation sequencing
• emerging pandemic viral threats
• respiratory viruses
• transplant viruses
• chronic viral infections
• cancer-associated viruses
• gastrointestinal viruses
• central nervous system viruses
• one health (excludes animal health)
