5/ The CDC recommends subtyping all hospitalized flu A+ cases. With H5N1 still circulating widely in birds & cattle, monitoring remains critical—especially for patients with close animal contact, who face the highest risk.

4/ This suggests that, in Seattle, the 2024-2025 flu season has been driven by seasonal strains, with no H5N1 detected among this cohort of patients with lab-confirmed influenza A infections.

3/ So far, none of the samples tested have been H5-positive. All sequenced samples contained seasonal H3N2 or H1N1 viruses.

2/ In Dr. Alex Greninger’s lab at UW Virology, we developed a clinical RT-qPCR assay for H5 subtyping. We used it to differentiate seasonal influenza A infections from subtype H5 infections during Seattle’s 2024-2025 influenza season.

1/ How has H5N1 affected this year’s flu season in Seattle? Despite ongoing outbreaks in birds & cattle nationally, we detected zero H5N1 cases in 675 influenza A-positive specimens tested at UW Medicine.
