H5N5 human case
1 BP difference in H5 from
A/Washington/2148/2025 | 11/10/25
These two sets of seqs represent
Pacific Flyway version of H5N5 genotype 6

NVSL uploaded 223 sets of H5N1 seqs and 5 sets of H5N5 seqs to GISAID
4 of the H5N5 sets were a novel genotype from the midwest
1 was genotype A6
A/turkey/Washington/04434-001-v/2025 | 11/14/25
and was closely related to the human H5N5 seq
A/Washington/2148/2025 | 11/10/25

NVSL uploaded 54 more sets of H5N1 seqs to GISAID wild birds and poultry
includes location and collection dates

The turkey vulture w/ PB2 E627K is also from NJ
A/turkey vulture/New Jersey/009512-006/2025 | 3/12/25

The cat developed severe disease
neurologic signs
euthanized
Other cats on the same property were also reported ill

One full seq from above cat cluster was uploaded today
A/cat/New Jersey/007151-003/2025 | 2/26/25

Matched earlier seqs
all had PB2 E627K
