SARS-CoV-2 variants for Japan
Here's the latest variant picture for Japan, showing the most common individual lineages. EG.5.1 (18%) is showing strong growth - it appears to be driving the current surge in hospitalisations.
EG is an alias for XBB.1.9.2.1, from the "Hyperion" clan. Along with several prior generations of mutations, EG.5 added the Spike F456L mutation, then EG.5.1 itself added the Spike Q52H mutation.
EG.5 was the first lineage mentioned last month's edition of the Neher Lab's variant report:

EG.5 was recently designated a "Variant Under Monitoring" (VUM) by the WHO.

The sample volumes seem representative up to June 30.
EG は別名XBB.1.9.2.1,で、"Hyperion"族である。幾つかの前の世代の変異に伴い、EG.5はF456Lのスパイク変異を獲得した。その後EG.5.1自体がQ52Hのスパイク変異を獲得した。
EG.5 は先月版のNeher Labの変異株レポートで最初に言及された変異株である。
EG.5は先ごろWHOの”Variant Under Monitoring" に指定された。
注)Neherラボの変異株レポートというのは、皆さまお馴染みの、@CorneliusRoemer さんの変異株レポートです。
