Agreed--We need more #histmed emoji! How are we supposed to represent a noxious miasma on social media--🌫️? 🌁?!

Ryan North@ryannorth.ca

why are there several emoji for blood (🩸🅰️🆎🅱️🅾️) yet no emoji accounting for excesses of the other three humors? for phlegm, nothing. for yellow bile, nada. and for black bile, zippo. an astonishing oversight

2. Schmitt's story is part of a larger story about the Republicans defending the leader of a coup against an investigation that, as Jack Smith said, "developed proof beyond a reasonable doubt that President Trump engaged in serious crimes against our nation."

Another strange thing about this article in the CDC’s peer-reviewed journal is that because the author used chatgpt to research it, it does not cite the CDC’s own research on smallpox and instead pulls random numbers from my book and some other odd sources.

I’d like to be flattered for being cited so extensively in the cover story for the most recent issue of the CDC’s journal Emerging Infectious Diseases, which features an article on George Washington’s decision to inoculate the Continental Army. wwwnc.cdc.gov/eid/article/...

It also likely shows the politics of the current CDC because it does not mention that inoculation was introduced in America by an enslaved Black man named Onesimus. Instead it cites me as it credits Cotton Mather. My book mentions Mather but credits Onesimus.

I could go on and on, but the piece does perhaps surprisingly fully endorse government efforts to inoculate citizens, writing that “[Washington’s order] was an effective, organized public health intervention, demonstrating the capacity of centralized authority to manage disease on a large scale.”

But the article is very odd. For one it acknowledges that the author used chatgpt to research it (why not reach out to me and have me or another expert write it?)

Love ye your neighbours?—let that love be shown Risk not their children while you guard your own -Robert Bloomfield, 1804, "Good Tidings, Or, News from the Farm," a tribute to smallpox vaccination

As bad as this is for science and for health, it’s also fundamentally unamerican to be opposed to vaccination and vaccination research. George Washington called for "a Law to compell the Masters of Families to inoculate every Child born within a certain limitted time under severe Penalties."

"Vats of vaccine are currently pumped into your child's body" -- Trump from the Oval Office is pushing debunked claims about vaccines and autism being linked

After calling for the inoculation of the Continental Army, Washington wrote: “I shudder when ever I reflect upon the difficulties of keeping [smallpox] out [without inoculation].”

All the Founders would be aghast J. Adams: “To disarm the Small Pox of its contagion [via vaccine] is an enterprize worthy of a Hercules in medicine.” T. Jefferson: “every friend of humanity must look with pleasure on this discovery, by which one evil is withdrawn from the condition of man.”

If Abdul El-Sayed wins the primary in Michigan today and goes on to win in November, he will be the first Democratic Senator to hold and medical degree and be a public health expert since Sen. Royal Copeland (former NYC health commissioner) died in 1938.

*You might say, "AHA! Wehrman doesn't know what he's talking about! What about Senator Ernest Gruening (1959-1969)?” Well, Gruening did graduate from Harvard Medical School in 1912, but he never practiced medicine or served in a health department and instead made his career in journalism.

In recent decades Republicans have elected several physcians, who mostly come from backgrounds in private medical practice (Mehmet Oz, Rand Paul, Bill Cassidy, Roger Marshall, etc.) and have used their Senate careers to vote against public health initiatives and national healthcare programs.

But the Democratic Party which passed Social Security, Medicare, Medicaid, and Obamacare has somewhat oddly not had a physician, epidemiologist, or other public health doctor in the Senate since Royal Copeland.* Fighting RFK jr. and health misinformation seems to require real expertise in the Senate

Glad to see my friend and former Marietta College colleague standing up against the terrible damage fracking is causing in Southeast Ohio. I can’t tell you how many times I was gaslit when I lived there about how safe it was. www.nytimes.com/2026/07/29/c...

YIKES! I always had this worry when doing my research but fortunately never ran into anything like this. I did question how I should be handling doctors’ notebooks from a smallpox hospital that looked like they hadn’t been opened in centuries, but luckily no scabs.

Historian friend was reading a civil war era letter in an archive, the letter said “In this envelope I include my smallpox scabs” and sure enough there they were. Had to call CDC for a hazmat team.

Probably more helpful to think of them not so much as “Canadian wildfires” but rather “climate change wildfires currently consuming Canada”

Enjoy fireworks on the 4th? Thank vaccines for making this (still dangerous) activity safer! Before routine vaccination for tetanus in the 1940s, the patriotic spirit every 4th of July was muted shortly thereafter when newspapers reported deaths from lockjaw (aka tetanus) in the days that followed.

Much is made of the 27 grievances in the Declaration and how some of them are thin or contrived. It’s really a wonder that blaming the King for spreading smallpox among them. It was widely thought that the British army was purposely trying to infect both the Continental Army and the American people🧵

At the same time, Jefferson worried about Virginia Governor Lord Dunmore’s efforts to give Virginia’s slaves freedom in exchange for fighting against the rebels. Jefferson learned that many slaves caught smallpox and feared Dunmore was using them to spread disease.

So it really is a wonder why smallpox didn’t make it in to Jefferson’s draft of the Declaration of Independence. Smallpox was certainly on the mind of nearly every colonist in 1775-1776 and blaming the British added anger and urgency to a growing movement for military action and independence.

After the American invasion of Canada failed spectacularly due to an outbreak of smallpox among the American soldiers, Congress held investigative hearings in July 1776, the first congressional investigation in US history. Jefferson, as if he wasn’t busy enough in June and July 1776, chaired it.

The committee concluded that the British purposely infected Canadians (inoculated them) for the purpose of spreading disease to the Army. Again, the evidence for this was thin at best.

In Boston in March 1775 in the last town meeting before the Battle of Lexington and Concord, the public learned that the British Army had been keeping known smallpox cases secret. This came after British officers had been caught inoculating contrary to Boston’s quarantine ordinances.

Rumors swirled during the siege of Boston that General Howe was sending out poor Bostonians who were infectious to try to spark an epidemic. Washington came to believe these rumors. There’s no good evidence the British intended this but it was widely believed.
