Open Street Maps might be seeing some trouble according to their LinkedIn, as further attacks on open data increase. OSM has been absolutely critical to public health and public service tools for years. #MapSky #geography

Before anti-vaxxers we had HIV denialists. It is wild how history repeats itself. Reading this piece is like traveling back in time. So many similarities with what we are witnessing right now with the anti science anti vaccine brigade. History repeats itself, we keep choosing not to learn from it.

🧪 Epi Explained: Herd Immunity 🛟 This week we're breaking down how herd immunity actually works, and why high vaccination coverage matters for protecting entire communities, including people who can’t be vaccinated. Quick, clear, and a little spicy at times. buff.ly/Hm86fgh #PublicHealth #IDSky

please remember that no matter how many “ICE is losing in MN” articles you read today, there is still a very real, urgent, ongoing crisis in Minnesota. people need food and they need rent money. that has not changed.

The climatologist told me historians will wonder why we didn’t do more. The epidemiologist told me historians will wonder why we didn’t do more. The activist told me historians will wonder why we didn’t do more. The historian told me that nobody listens to historians.

What's the difference between Swine Flu and Bird Flu? One requires Oinkment, the other requires Tweetment.

🚨 The WH is now using disasters to take away state’s rights. Read this thread while it is still allowed.

I sent my friend an article about how the “US government has lost more than 10,000 STEM PhDs since Trump took office,” and my friend (who is one of those 10,000) replied that: “lost” is a funny way of spelling “were fired or driven out.”

To quote many a social movement, "Silence is violence", and friends, they're trying to commit violence against you in ways that should have been left in the history books.

Infectious diseases do not magically disappear just because you stop tracking and reporting. This is dangerous. When diseases spread in silence, outbreaks go undetected for much longer and containment is more difficult. All of this means more avoidable deaths. www.medpagetoday.com/infectiousdi...

May he rest, and his work continue on!

There is a cost to science denial.

The UK has lost its measles elimination status, the World Health Organization has announced. Vaccine disinformation is a worldwide pandemic that is killing us.

American Life Insurance Companies have a fantastic ability to do a psy-op on ICE by simply not allowing a policy for anyone who works with ICE/DHS due to "extreme risk". I'd certainly think carefully about my actions if I knew my loved ones would be on their own if I bit the big one.

A useful infographic for protestors. Actually, with my background in CBRN/Public Health, would a community guide to identification and remediation of chemical agents be of interest?

People are right to be incensed, but there are more names to uplift. ICE killed an immigrant man named Silverio Villegas González in Chicagoland. He had children. Victor Manuel Diaz was kidnapped in Minneapolis and died in ICE custody on January 14. Their names deserve to be repeated, too.

One of the best things I’ve read in a while:

We’re airing a new campaign ad, starting tomorrow. Here it is:

A lot of good Mutual Aid work often looks similar to a lot of Public Health work: Often it's quiet, mundane, but absolutely foundational to success. When you start hearing about everything going on (and you aren't already directly involved), that's when things are getting very messy.

The nurses are pissed

William Foege has died. He was a central architect of smallpox eradication, pioneering surveillance-driven ring vaccination when vaccine supply was limited. That strategy helped eliminate the deadliest human pathogen we’ve ever known. www.nytimes.com/2026/01/24/u...

If they are doing this to white people in broad daylight imagine what they are doing to non-white people in detention facilities.

Years ago, in the wake of Breonna Taylor and George Floyd, I wrote to suggest that judges refuse probable cause/deny warrant applications as a violence reduction strategy. It was focused on state courts and militarized searches, but is relevant to now, too. papers.ssrn.com/sol3/papers....

Fun fact, back during the days of bigger BLM marches, this and self-quarantine prevented what would have been huge COVID outbreaks. Dr. Tran has it right. For both operational and health security, wear an n95 (or the closest you can get).

I keep hearing people say in response to all the horrors of this world that “this too shall pass,” but I keep seeing studies revealing how Covid has changed our brains and bodies and I am worried oh, I am very worried, that it shall not actually pass.

Should they respond (and they likely will) to your comments on this ongoing pandemic by suggesting that you and people like you “are insufferable,” politely but firmly reply that what you and people like you are trying to prevent is suffering.

It's wild that so many of these people who Support ICE have been the sorts to tout things like Stoicism online, but they forgot perhaps the most important line in all of Stoicism. "All cruelty stems from weakness"- Seneca. These are the men we were warned of. Weak men make for bad times.

Not a historian, but I remember things going very poorly for those in charge when: 1. People stopped fearing secret police and worked together. 2. When people noticed those who ignored the law of the land weren't punished 3. When people couldn't afford food. Wild, could never happen here.

My friend, the climatologist, told me this year is off to a bad start. My friend, the epidemiologist, told me this year is off to a bad start. My friend, the historian, told me this year is just getting started.

Couldn't be happier to see Tuskegee 2.0 being canceled; It would have been of no benefit and caused untold suffering.

An old friend called asking about precautions and after providing what advice I could I asked “why now?” and my old friend explained that with the premiums on his health insurance rising he just can’t afford (he just knows he can’t afford) to get sick again.

Insidious and dangerous erosion of evidence based guidelines. Nothing if off limits. The scale of public health destruction we are witnessing will take decades to reverse if at all.

Cutting naloxone, outreach, and recovery grants during an overdose emergency makes deaths both foreseeable and preventable -- falling hardest on the most marginalized. This is a profound ethical failure. www.npr.org/2026/01/14/n...

This thread is absolutely worth the read, especially if you aren't very well versed in methods of de-escalations in high stress group settings.

It's worth noting that the current administration is for sure not above using hunger as a weapon against states they don't like. If you can, check up on friends and family who rely on food stamps and make sure they can be supported as much as is possible.

More people are surviving cancer than ever before, according to new report www.statnews.com/2026/01/13/w... via @statnews

The EPA says that it will now ignore health benefits and lives saved, and instead only factor in business costs when making new rules on air pollution limits. This is so reckless and make us all sicker.
