Abstract

Foot-and-mouth disease virus (FMDV) serotype Asia1 is prevalent in India and is responsible for a minor proportion of FMD outbreaks. Globally, serotype Asia1 is grouped into nine different groups (GI-IX) based on genetic analysis. In India, only Asia1/G-III and Asia1/G-VIII have been documented so far. Phylogenetic analysis of recent serotype Asia1 isolates from India revealed the emergence of Asia1/G-IX. The Asia1/G-IX lineage shares recent common ancestry with Asia1/G-VIII dating to 2016. The root state posterior probabilities of Asia1/G-VIII are inclusive and there may have been either an incursion of the virus from Bangladesh, where it was first identified, or in situ evolution of the virus within India, which is an intriguing possibility.
