The updated US SARS-CoV-2 genomics shows a sharp increase in the NB.1.8.1 variant, and to a lesser extent XFG (combine w/ XFC).
It remains to be seen how much these, especially NB.1.8.1, can lead to a significant rise in cases here, as was seen in Asia.

We're making viruses from public opinions! At #GERF2025 we're asking the public if they would take part in a human challenge study: green for yes, red for no, and blue for maybe. The mix of opinions is fascinating and it's clear there's a hunger to know more! 🧪@imperialinfect.bsky.social, @cepi.net

My co-EIC Florian Krammer wrote this commentary in Vaccine on the need for next generation flu vaccines to have a NA component (the N in H5N1 or H3N2).
It’s a smart idea & safeguards against bad matches to HA & other subtypes that share N1 or N2.

The threat of avian influenza H5N1 looms over global biodiversity - Nature Reviews Biodiversity
The highly pathogenic avian influenza H5N1 is an emerging and unexpected threat to many wild animal species, which has implications for ecological processes, ecosystem services and conservation of threatened species. International collaboration and information-sharing is essential for surveillance, early diagnosis and the provision of financial and technical instruments to enable worldwide actions.
