Here's the latest variant picture for the "Global - Other" countries, to mid-June.
The NB.1.8.1 "Nimbus" variant was steady at 51%.
XFG.* "Stratus" grew to 21%.
The volatility is due to the ragged timing of submissions from various countries.
This perspective excludes all the high-volume countries and regions that I routinely report on: Australia, NZ, Europe, Canada and the US. The remaining countries are aggregated into this report.
