Here's the latest variant picture for South Australia.
The next challenge to EG.5.* "Eris" (56%) looks like either XBB.1.5.* "Kraken" (16%) or BA.2.86.* "Pirola" (10%), which looks to have started community transmission.
The new EG.5.* "Eris" variant (34%) has been rising quite rapidly during July, and is now dominant over XBB.1.9.* "Hyperion" (22%), XBB.1.16.* "Arcturus" (14%), XBB.1.5.* "Kraken" (14%) and XBB.2.3.* "Acrux" (13%).
The sample volumes seem representative up to July 17.
The new EG.5.* "Eris" variant (58%) has been rising rapidly, bursting clear of the usual "XBB soup" variants.
In 2023 it has been quite unusual to see a single variant achieve > 50%, in any country. Ireland is currently reporting EG.5.* at the highest frequency seen anywhere.
The sample volumes seem representative up to July 29.
Here's the frequency of EG.5 in the Australian states recently. There are only a few scattered samples up to early June, so perhaps this parent lineage has died out.
No nickname has been considered for this lineage yet, but FWIW I'm thinking of EG.5 as "Egg".
