Here's the latest variant picture for the United States, to late April.
The LP.8.1.* variant appears to have peaked and fell back to 54%.
#COVID19 #USA #LP_8_1 #XFG #XDV
🧵
The presumed next challengers are growing – XFG.* to 11% and XDV.* (led by NB.1.8.1) to 6%.
🧵
For the US, the XFG.* variant shows a strong growth advantage of 5.6% per day (39% per week) over LP.8.1.*, which predicts a crossover in late May.
🧵
For the US, the NB.1.8.1 variant shows a healthy and accelerating growth advantage of 5.1% per day (36% per week) over LP.8.1.1, with a possible crossover in late May.
🧵
Here's the latest variant picture with a global scope, to late April.
Growth of the LP.8.1.* variant is holding at around 39%.
XDV.* (led by NB.1.8.1) looks like the next challenger, rising steadily to 13%
#COVID19 #Global #LP_8_1 #XDV #NB_1_8_1
🧵
Globally, the XDV.* variant clan (led by NB.1.8.1) is showing a strong but slowing growth advantage of 5.1% per day (36% per week) over the dominant LP.8.1.* variants. That now predicts a crossover in late May.
Strong growth advantages point to higher waves than for LP.8.1.*.
🧵
NB.1.8.1 was initially reported from Hong Kong, rising to 100% frequency. It has also shown sustained growth in several other countries in the region, plus Canada and the US - all adding to its credibility.
🧵
With the LP.8.1.* variant dominant from the global perspective, it is time to ponder which variant might drive the next wave.
The leading contenders at this point are XDV.* (led by NB.1.8.1), and XFG.*.

🧵
I show them above using a log scale, so you can compare their growth rates vs the dominant LP.8.1.*. Note the recent sample volumes are quite low, so the right side of this chart might not be a representative picture.
🧵
NB.1.8.1 is descended from XDV.1.5.1. XDV was a recombinant of XDE and JN.1. XDE was a recombinant of GW.5.1 and FL.13.4 (both descended from XBB), so this represents the last current variant with any non-JN.1 ancestry.

Growth of the LP.8.1.* variant appears to have peaked, and fell to around 39%.
XDV.* (led by NB.1.8.1) looks like the next challenger, rising strongly to 11%
#COVID19 #Global #LP_8_1 #XDV
🧵
Globally, the XDV.* variant clan (led by NB.1.8.1) is showing a strong growth advantage of 5.5% per day (39% per week) over the dominant LP.8.1.* variants. That predicts a crossover in mid-May.
That could point to higher waves than those seen for LP.8.1.*.
