Lineage that's surging in the #UnitedKingdom now. CH.1.1* is already at 1% in NY.

#H5N1 #LessonLearned - Domestic and Farm cats!

Common theme among H5N1 clade 2.3.4.4b infected Cats:
- Present multiple symptoms almost immediately
- Neurologic, Respiratory, rapid decline leading to death
(or compassionate euthanasia)
- Pick PB2 mammalian adaptations

1/n Image
French Cat (2022)

Phylogenetic analysis linked the infection closely to virus circulating in the neighboring duck farm, with minor genetic differences.

Key mutations: PB2 E627K & NS: E26G

Again, rapid selection of mammalian adaptation mutation

2/n
Polish Cats (2023)

First widespread H5N1 clade 2.3.4.4b infection across a wide geographic area within a country

Outbreak affected both indoor/outdoor cats

Cat food/ Stork investigated as a likely sources

Mammalian adaptations: PB2 E627K & K526R

JN.1* is still the dominant circulating group of lineages

Expected JN.1.11.1* sub-lineages (KP*) and others with #FLiRT mutations to feature in the dashboard

#FLiRT lineages are growing 👀

Nearly 20% of JN.1.13 (listed in CDC dashboard) is KS.1 (JN.1.13.1.1; not separated from the parent lineage yet)

and 55% of JN.1.16 is JN.1.16.1

Both KS.1 and JN.1.16.1 are #FLiRT lineages
