“Communication is the most important public health intervention we have.” – @JenniferNuzzo @NOTUSreports: Threats like #H5N1 depends on strong federal-state ties. Restricting the @CDCgov risks data gaps & public mistrust. More here 👇
State health departments are giving mixed signals on what they’ve heard from the Trump administration on H5N1, with some officials and experts concerned about a lack of communication. notus.org/policy/bird-fl…
I spoke with @meghanbartels @sciam about why we aren’t seeing as much H5N1 bird flu in the US right now (link in replies). Part of it might be seasonal, but a big part of it is reduced testing and surveillance. Complements this piece I wrote just yesterday, w/ @JenniferNuzzo.
It's hot dead raccoon summer so maybe we should keep an eye on these mammals (link in first reply)
I deleted a tweet that often draws criticism. Not because I'm embarrassed by it (though, I should have been more nuanced). But because I'm trying to see if twitter stands by it's policy to kick off people who post screenshots of deleted tweets.
More evidence that Epstein-Barr virus infection is implicated in multiple sclerosis onset. That’s why our work @ARPA_H to eliminate herpesviruses, to include EBV, is so critical. Follow our teams at @UWproteindesign and @ljiresearch for more!
Here are billions of dollars in canceled NIH grants for childhood immunizations.

Whether or not you care about foreign aid, you should be very worried about what DOGE is doing to @USAID right now. Breaching highly classified systems and unlawfully attempting to unilaterally dissolve an independent federal agency. This is a test run. 🧵
“Musk’s DOGE crew lacked high-enough security clearance to access that information, so the two USAID security officials — John Vorhees and deputy Brian McGill — were legally obligated to deny access.” apnews.com/article/doge-m…
Adding to this— the unelected employees have multiple on-going business interests with foreign governments. And they are attempting to access classified information. This has major national security implications.
No one elected Elon Musk. As Donald Trump allows Musk to access people’s personal information and shut down government funding, Republicans in Washington will also own the consequences. We must do everything in our power to push back and protect people from harm.
NEW: Top USAID security officials put on leave after DOGE officials showed up last night demanding entry. Threatened to call US Marshals, looking to access to security systems, personnel files and classified information, sources tell @jmhansler & me cnn.com/2025/02/02/pol…
"When CDC can't even talk to our health officials they can't fulfill their statutory obligation to protect America's health." @JenniferNuzzo joined @CNN @VictorBlackwell to discuss the removal of data and information from CDC webpages. Watch here 🎥: youtube.com/watch?v=v7Lfmc…
“People might think ‘It’s just a data set,” said Dawes. “It’s more than a data set, it’s years and years of collecting data, analyzing data, and putting it into a format that communities can use, literally, to extend their lives.” statnews.com/2025/02/01/cdc…

Organizations that provide life-saving humanitarian aid deserve clarity from @StateDept — not additional chaos and confusion. I call on @SecRubio to rescind the federal foreign aid freeze so we can promote American national security and interests.
MMWR is the voice of science. The delay in publishing is dangerous. kffhealthnews.org/news/article/c…
I am disheartened that several CDC webpages are currently down. I hope this is just a temporary pause. Infectious diseases don't take breaks. The American taxpayers who paid for these data deserve the ability to access the lifesaving information derived from these data.

In this piece I’m quoted about the fact that there’s no evidence that different racial groups should be on different vaccinations schedules. Such unfounded assertions can drive vaccine hesitancy apnews.com/article/rfk-jr…
I spoke with the NYT about the damning evidence we uncovered against RFK Jr. while making my latest film. As we show in the film, RFK Jr. played a significant role in a tragic measles outbreak in Samoa that led to 83 deaths, mostly amongst children. nytimes.com/2025/01/28/us/…
