NEW: The CDC has been in crisis for months. After the firing of its director, resignations of senior leaders, staff + experts are bracing for what could be death knell for public health credibility. Me + @laurenweberhp.bsky.social + @davidovalle.bsky.social www.washingtonpost.com/health/2025/...

The CDC is falling deeper into crisis. What it means for the nation’s health.

Months of upheaval at the Centers for Disease Control and Prevention have undercut the agency’s work, employees said, and put the future of vaccines into doubt.

Demetre Daskalakis is an absolute GOAT of modern US public health, he should be the next head of the CDC and subsequently a US senator

only so many words you can put in a headline but the whole response is loud and proud support for the trans community and worth reading

Given the chance to respond to Leavitt’s remarks by Collins on the Thursday The Source, Daskalakis said, “I have for my entire career been an advocate for the LGBTQ community... I find it outrageous that this administration is trying to erase transgender people.”

“I very specifically used the term pregnant people, and very specifically added my pronouns at the end of my resignation letter to make the point that I am defying this terrible strategy at trying to erase people and not allowing them to express their identities,” he continued.

“So I accept the note from the press secretary, and counter that with: I don‘t care.”

tl;dr: Fall vaccines are anything but business as usual this year and all eyes will be on independent orgs and health insurance companies.

It's exceedingly hard to argue that the administration & MAHA are committed to improving nutrition when they're simultaneously cutting everything from SNAP-Ed to innovative community nutrition work - cements the perception that food dyes are public health theatre.

This week, @texasmonthly.bsky.social’s reporting on the floods in Kerr County has been so purposeful and so deeply empathetic. It was personal. This first person account is so, so horrific and so beautifully written.

Sadly, I agree with most of this and it is nicely described and illustrated. Its clever to position the "hits" after the mid-term elections. This causes a challenge of how to describe the issue when its not being felt yet.
