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
🧵 Image
The presumed next challengers are growing – XFG.* to 11% and XDV.* (led by NB.1.8.1) to 6%.
🧵 Image
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.
🧵 Image
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.

The Provisional Mortality statistics have been updated by the Australian Bureau of Statistics (ABS), up to January 2025.

Here are the deaths where the underlying cause of death was certified by a doctor as COVID-19 (22,357 deaths).
#COVID19 #Australia
🧵
Each individual death is represented by a single point, spread out across the years of the pandemic.

A relative low wave of COVID-19 deaths peaked in early January 2025, driven by the XEC.* variant.

🧵
The visual is also available as a vertical scrolling page, which gives a more detailed perspective.

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
🧵 Image
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.*.
🧵 Image
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.*.
#COVID19 #NB_1_8_1 #XFG
🧵 Image
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.

Here's the latest variant picture for the United States, to mid-April.

The LP.8.1.* variant growth continued to around 61%, but may have peaked.

The presumed next challengers – XFG.* and XDV.* (led by NB.1.8.1) are still below 5%.

#COVID19 #USA #LP_8_1 #XFG #XDV
🧵 Image
Image
For the US, the XFG.* variant shows a strong growth advantage of 5.9% per day (41% per week) over LP.8.1.*, which predicts a crossover in late May.
🧵 Image
For the US, the NB.1.8.1 variant shows a healthy growth advantage of 4.3% per day (30% per week) over LP.8.1.1, with a possible crossover in June.

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.*.

#COVID19 #NB_1_8_1 #XFG

With the splintering of XFG.* into sub-lineages, I have switched my analysis to my variant “L2” groups.

I show them here 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.
