Ecology and spread of the North American H5N1 epizootic - Nature The panzootic of highly pathogenic H5N1 since 2021 was driven by around nine introductions into the Atlantic and Pacific flyways, followed by rapid dissemination through wild migratory birds, primaril...

Our lab's paper describing the North American H5N1 epizootic is out now in Nature! So thrilled to have this out, and congratulations to @lambod50.bsky.social for all the fantastic work on this: www.nature.com/articles/s41...

Thanks for sharing! We're super excited we could play a role in this project. Wastewater genomic surveillance has proved to be an valuable tool in the public health world!

CDC leaders attempt to reassure staff after shooting, but meeting is brief An all-hands meeting at the CDC to discuss the attack on the agency on Friday was brief and chaotic, staffers say.

Rocky start for new #CDC director Susan Monarez, whose first week was punctuated by Friday's attack. Her first all-hands meeting lasted ~13 minutes, with technical challenges with dead air for a time & some staff unable to join the call. "This is a mess," one said. www.statnews.com/2025/08/12/c...

@kevinlibuit.bsky.social & @curtiskapsak.bsky.social were two of the co-authors on a new paper on Freyja 2 — a bioinformatics tool for real-time, multi-pathogen wastewater surveillance.

A few days ago we preprinted our Freyja 2 paper, describing the expansion of our original Freyja method to a real-time, multi-pathogen surveillance tool to track pathogen lineage prevalence and dynamics from sequencing of wastewater and other complex samples (like milk). 🧵

Pleased to say that our preprint benchmarking Nanopore data for MLST, cgMLST, cgSNP & AMR typing from bacterial isolates is out! TL;DR you can get almost perfect results from 50x depth using live SUP basecalling with a GPU in under 20 hours #microsky#IDsky 🦠🧬🖥️ /1

Congrats to you and the team that put this all together. So excited to dive deeper and utilize those datasets. Thank you all so much!!

Schrier to RFK Jr: You gave Cassidy the answer he needed to hear in order to get his confirmation vote, then as soon as you were secretary you turned around & fired all 17 members. You lied. I also want to be clear that I will lay all responsibility for every vaccine-preventable death at your feet.

RUIZ: Did you read the report & fact-check its sources prior to publication?

RFK JR: I did not fact check

RUIZ: It included citations to sources that don't exist. How does that happen?

RFK JR: All of the foundational assertions are accurate

RUIZ: They did not exist. How can they be accurate?

You might be wondering why we haven't updated outbreak.info for months.

Well, the reason is that GISAID cut our access in January - as they did others. Without telling us.

After a ♾️ back and forth, that is now permanent.

More on that soon - and why GISAID should not be trusted with critical data.
