Proud to have played a small role in this work regarding the linking of SARS-CoV-2 WGS data with epidemiological data for >800k samples! California's COVIDNet program & IGED has enabled impactful studies and actionable public health insights. Can't wait to expand to other pathogens!

Excited to share a preprint on how CA linked almost 1 million SARS-CoV-2 sequencing data to the patient data. This was a huge effort by multiple groups and we hope this can be used as a model for other emerging pathogens to enhance genomic epidemiology. www.medrxiv.org/content/10.6...

The CDC warns that extensively drug-resistant (XDR) Shigella is on the rise in US. The prevalence of XDR Shigella isolates in US surveillance data rose from 0% during 2011-2015 to 8.5% in 2023. Read more: ow.ly/VXee50YLphl 📷: CDC, Stephanie Rossow

Sorry, kid, the government cancelled research into a cure for your disease. The man who swims in sewage and snorts cocaine in public restrooms said it's bad for you. Besides, there's no money now that we're locking up your friend's parents and the guys who mowed our lawn.

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...

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.

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). 🧵  doi.org/10.1101/2025...

Real-time, multi-pathogen wastewater genomic surveillance with Freyja 2

Case-based infectious disease surveillance is fundamental to public health, but is resource-intensive, logistically complex, and prone to sampling bias. Wastewater testing and sequencing have increasi...

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.
