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.

在印度出现了口蹄疫病毒血清型Asia1 IX组。

亚洲地区的口蹄疫病毒（FMDV）血清型Asia1在印度很普遍，并且是口蹄疫爆发的一小部分。在全球范围内，基于基因分析，亚洲血清型1被分为9个不同的组（GI-IX）。在印度，到目前为止，仅记录了Asia1 / G-III和Asia1 / G-VIII。对来自印度的最新血清型Asia1分离株的系统发育分析表明，出现了Asia1 / G-IX。Asia1 / G-IX血统与Asia1 / G-VIII有着近来的共同血统，可追溯到2016年。Asia1/ G-VIII的根源后验概率是包容性的，并且可能是孟加拉国入侵了该病毒最早被发现，或者是印度境内病毒的原位进化，这是一个有趣的可能性。
