Jimmy Carter has had many accomplishments, but nearly eradicating Guinea worm may be his greatest
It was a problem no one would touch.

In 2015, former president Jimmy Carter held a press conference where he laid out a goal for the rest of his time on Earth. "I would like to see Guinea worm completely eradicated before I die," Carter said. "I'd like for the last Guinea worm to die before I do. I think right now, we have 11 cases. We started out with 3.6 million cases."
Now that Carter, 98, is in hospice, spending his final days at home with his family, he probably won’t achieve his goal. But his herculean efforts at abolishing the deadly worm will be ranked among his most significant achievements as a politician and humanitarian over his extraordinary life.
When the Carter Center took the lead on an international campaign to eradicate the Guinea worm in 1986, there were 3.5 million cases in 21 countries across Africa and Asia. In 2022, only 13 cases were reported worldwide, a 99.99% decrease. If the Guinea worm disease is completely eradicated, it would only be the second eradicated human disease in history, following smallpox.
Carter and his wife celebrated a record low in cases last year.
“Rosalynn and I are pleased with this continued advance toward eradicating Guinea worm disease,” President Carter said. “Our partners, especially those in the affected villages, work with us daily to rid the world of this scourge. We are heartened that eradication can be achieved soon.”
After Carter left the White House in 1981, he went on a mission to fight “neglected” diseases in far-off places that most Americans would never have to worry about. He set his sights on conditions such as lymphatic filariasis, trachoma, river blindness, and schistosomiasis.
His former drug czar Peter Borne brought Guinea worm to his attention. Borne approached the Carter Center because no one else would touch the problem.
Guinea worm is also known as dracunculiasis which means “affliction with little dragons” in Latin. About a year after infection, the worms grow to three feet long, and the females prepare to give birth by making their way to a place right below the skin, causing painful blisters.
Eventually, the blisters burst and the mother burrows her way out, causing incredible pain.
To ease the pain, people often submerge the affected area in water, causing tens of thousands of baby worms to release in the water, where they will eventually find a host. Guinea worm can also cause fever, swelling and secondary infections like sepsis. Guinea worm causes significant hardships for families by rendering people unable to work or attend school.
“It’s an audacious and mind-boggling idea,” said Emily Staub, press liaison to health programs for the Carter Center, according to CNN. “I’m not just talking about just him. I’m talking about a whole bunch of people with the Carter Center that decided that they were going to eradicate a disease that has no vaccine, no immunity, no medication. It’s thousands of years old and has a one-year incubation. The odds are totally stacked against you. And the people that suffer from it speak thousands of different languages, and some have never had outsiders interact with them.”

But Carter persisted, creating countless partnerships with leaders around the globe to educate people about the worm, provide tools for clean water and prevent its spread in the animal population. "Guinea worm disease has no cure, no vaccination, basically the entire eradication effort is built on behavior change,” Kelly Callahan, a public health worker who partnered with the Carter Center, told NPR.
Thirty-seven years after the Carter Center started on the audacious task of eradicating Guinea worm, the WHO has certified that 200 countries are free of the disease, meaning they've had zero instances of transmission in three years. Only six countries have yet to be certified as disease-free.
Jimmy Carter set a nearly impossible task, but with dogged persistence and the ability to make partnerships with people worldwide, many of whom have had little contact with the outside, he has helped save millions upon millions of people from incredible suffering.
In the coming days, people will celebrate many of Carter’s accomplishments. Let’s be sure that no one forgets to mention a success he’d rank among his proudest.
“We were traveling in a big motorcade,” he said in 2017. “We were driving along, and elementary school children had a big sign that says, ‘Watch out, Guinea worm. Here comes Jimmy Carter.’ That was almost as good as a Nobel Prize for me.”

There's a reason why some people can perfectly copy accents, and others can't
Turns out, there's a neurodivergent link.

Have you ever had that friend who goes on vacation for four days to London and comes back with a full-on Queen's English posh accent? "Oooh I left my brolly in the loo," they say, and you respond, "But you're from Colorado!" Well, there are reasons they (and many of us) do that, and usually it's on a pretty subconscious level.
It's called "accent mirroring," and it's actually quite common with people who are neurodivergent, particularly those with ADHD (Attention Deficit Hyperactivity Disorder). According Neurolaunch, the self-described "Free Mental Health Library," "Accent mirroring, also known as accent adaptation or phonetic convergence, is the tendency to unconsciously adopt the accent or speech patterns of those around us. This linguistic chameleon effect is not unique to individuals with ADHD, but it appears to be more pronounced and frequent in this population."
Essentially, when people have conversations, we're constantly "scanning" for information—not just the words we're absorbing, but the inflection and tone. "When we hear an accent, our brains automatically analyze and categorize the phonetic features, prosody, and intonation patterns," writes Neurolaunch. For most, this does result in copying the accent of the person with whom we're speaking. But those with ADHD might be more sensitive to auditory cues. This, "coupled with a reduced ability to filter out or inhibit the impulse to mimic…could potentially explain the increased tendency for accent mirroring."
While the article explains further research is needed, they distinctly state that, "Accent mirroring in individuals with ADHD often manifests as an unconscious mimicry of accents in social situations. This can range from subtle shifts in pronunciation to more noticeable changes in intonation and speech rhythm. For example, a person with ADHD might find themselves unconsciously adopting a Southern drawl when conversing with someone from Texas, even if they’ve never lived in the South themselves."
People are having their say online. On the subreddit r/ADHDWomen, a thread began: "Taking on accents is an ADHD thing?" The OP shares, "My whole life, I've picked up accents. I, myself, never noticed, but everyone around me would be like, 'Why are you talking like that??' It could be after I watched a show or movie with an accent or after I've traveled somewhere with a different accent than my 'normal.'
They continue, "Apparently, I pick it up fast, but it fades out slowly. Today... I'm scrolling Instagram, I watch a reel from a comedian couple (Darcy and Jeremy. IYKYK) about how Darcy (ADHD) picks up accents everywhere they go. It's called ADHD Mirroring??? And it's another way of masking."
(The OP is referring to Darcy Michaels and his husband Jeremy Baer, who are both touring comedians based in Canada.)
Hundreds of people on the Reddit thread alone seem to relate. One comments, "Omfg I've done this my whole life; I'll even pick up on the pauses/spaces when I'm talking to someone who is ESL—but English is my first language lol."
Sometimes, it can be a real issue for those around the chameleon. "I accidentally mimicked a waitress's weird laugh one time. As soon as she was out of earshot, my family started to reprimand me, but I was already like 'oh my god I don’t know why I did that, I feel so bad.'"
Many commenters on TikTok were shocked to find out this can be a sign of ADHD. One jokes, "Omg, yes, at a store the cashier was talking to me and she was French. She's like 'Oh are you French too? No, I'm not lol. I'm very east coast Canada."
And some people just embrace it and make it work for them. "I mirror their words or phrase! I’m 30. I realized I start calling everyone sweetie cause my manager does & I work at coffee shop."
