Evolutionary stasis of an RNA virus indicates arbovirus re-emergence triggered by accidental release

D. J. Pascall, K. Nomikou, E. Breard, S. Zientara, A. da Silva Filipe, B. Hoffmann, M. Jacquot, J. B. Singer, K. De Clercq, A. Botner, C. Sailleau, C. Viarouge, C. Batten, G. Puggioni, C. Ligios, , M. Palmarini

This study uses genomic data to show that a BTV-8 virus strain re-emerged in 2015 without significant evolution, suggesting accidental release rather than natural persistence.
