Imagine for a minute: A company makes a vaccine that protects kids from a life-threatening disease but, with little warning, decides to stop selling it in the U.S.

That's exactly what happened last year in West Africa, for a vaccine against rotavirus — a disease that kills about 200,000 young children and babies each year.

Six years ago, I was traveling in India, working on a story about measles. I was visiting a public hospital in New Delhi, when I walked into the waiting room and saw the tiniest baby I had ever seen.

An elderly woman — perhaps a grandma — was cradling the newborn in her arms. The little baby was wrapped in a blanket, and a tiny knit cap covered her head, which wasn't much bigger than a small orange. The newborn could not have weighed more than four pounds.

The U.S. Food and Drug Administration just approved one of the most sought after vaccines in recent decades. It's the world's first vaccine to prevent dengue fever — a disease so painful that its nickname is "breakbone fever."

The vaccine, called Dengvaxia, is aimed at helping children in Puerto Rico and other U.S. territories where dengue is a problem.

Is it possible to raise children without shouting, scolding — or even talking to kids with an angry tone?

Last month, we wrote about supermoms up in the Arctic who pulled off this daunting task with ease. They use a powerful suite of tools, which includes storytelling, playful dramas and many questions.

Measles is surging. Last week the U.S. recorded 90 cases, making this year's outbreak the second largest in more than two decades.

So far this year, the U.S. has confirmed 555 measles cases, the Centers for Disease Control and Prevention announced Monday. That's 50 percent higher than the total number recorded last year, even though we're only about a quarter of the way through 2019.

And the virus isn't slowing down.

Six months ago, I found myself preparing for battle.

I was lying in bed at 5:30 a.m., going over in my head how to handle the next encounter with my 3-year-old daughter, Rosy.

Goodness knows, I love her so much. But there's a fire in that little belly. And to be honest, I have no idea how to handle all the anger — the tantrums, the screaming and, most of all, the hitting.

When she's angry and I pick her up, she has a habit of slapping me across the face. Sometimes it really hurts. I've even started ducking like a boxer when I lift her up.

Back in the 1960s, a Harvard graduate student made a landmark discovery about the nature of human anger.

At age 34, Jean Briggs traveled above the Arctic Circle and lived out on the tundra for 17 months. There were no roads, no heating systems, no grocery stores. Winter temperatures could easily dip below minus 40 degrees Fahrenheit.

Briggs persuaded an Inuit family to "adopt" her and "try to keep her alive," as the anthropologist wrote in 1970.

Over the past three years, I've had one major goal in my personal life: To stop being so angry.

Anger has been my emotional currency. I grew up in an angry home. Door slamming and phone throwing were basic means of communication.

I brought these skills to my 20-year marriage. "Why are you yelling?" my husband would say.

"I'm not," I'd retort. Oh wait. On second thought: "You're right. I am yelling."

Several years ago, British entomologist Steve Lindsay landed at an American airport and was immediately struck by all the furry creatures walking around the baggage claim area.

"I was astounded to see sniffer dogs, looking for fruits and vegetables," says Lindsay, who studies malaria at Durham University in the U.K.

The pharmaceutical giant Merck & Co. Inc. is ending a long-term agreement to supply a lifesaving vaccine for children in West Africa.

At the same time, the company has started sending the vaccine to China, where it will likely be sold for a much higher price.

The vaccine is for a deadly form of diarrhea, called rotavirus, which kills about 200,000 young children and babies each year.

The rate of cesarean sections around the world is increasing at an "alarming" rate, reported an international team of doctors and scientists on Thursday.

Since 1990, C-sections have more than tripled from about 6 percent of all births to 21 percent, three studies report in The Lancet. And there are no "signs of slowing down," the researchers write in a commentary about the studies.

Maybe the short answer is: We need a better imagination?

The global health world hasn't set its goals high enough, hasn't dreamed big enough when it comes to stopping tuberculosis, says Dr. Paul Farmer, physician at Harvard Medical School and founder of the nonprofit Partners In Health.

"We've had a failure of imagination," he says. "We haven't had the same optimism, commitment and high ambitious goals around TB that we've seen around HIV. And what's the downside of setting high goals? I think it's very limited."

About a hundred years ago, something devious started happening in our homes and offices, in our cars and at restaurants — and our backs have never been the same.

For hundreds — even thousands — of years, chairs were made of wood. Maybe the seat was covered with cord or cattail leaves, and if you were rich, you could afford some padded upholstery, which began to take off in the 17th and 18th centuries.

If hadn't seen it with my own eyes, I wouldn't have believed it.

But there it was, right in front of me: A preteen voluntarily doing chores around the house.

There was no fuss. No nagging or whining. And there were no visible rewards.

I was visiting Maya families in the Yucatan, reporting for NPR's special parenting series #HowToRaiseAHuman. While I was interviewing one mom her 12-year-old daughter went over to the dishes and started washing away — without being asked.

My back hurts when I sit down.

It's been going on for 10 years. It really doesn't matter where I am — at work, at a restaurant, even on our couch at home. My lower back screams, "Stop sitting!"

To try to reduce the pain, I bought a kneeling chair at work. Then I got a standing desk. Then I went back to a regular chair because standing became painful.

I've seen physical therapists, orthopedic surgeons and pain specialists. I've mastered Pilates, increased flexibility and strengthened muscles. At one point, my abs were so strong my husband nicknamed them "the plate."

The world now has a potent, new weapon against malaria — one that can wipe out the parasite from a person's body with a single dose.

But before many people around the world can use it, scientists have to overcome a big obstacle.

After a woman gives birth to her baby, labor is not over. She also has to birth the placenta, and this can be quite risky.

The placenta attaches to the uterus through a series of blood vessels, which reach from the mom into the placenta. After childbirth, the placenta tears off the uterus, leaving these vessels open and exposed.

Back in the early 1990s, psychologist Suzanne Gaskins was living in a small Maya village near Valladolid, Yucatán, when she struck up a conversation with two sisters, ages 7 and 9.

The girls started telling her — with great pride — about all the chores they did after school. "I wash my own clothes," the 7-year-old said. The older sister then one-upped her and declared, "I wash my clothes and my baby brother's clothes."

Six months ago, Melissa Nichols brought her baby girl, Arlo, home from the hospital. And she immediately had a secret.

"I just felt guilty and like I didn't want to tell anyone," says Nichols, who lives in San Francisco. "It feels like you're a bad mom. The mom guilt starts early, I guess."

Across town, first-time mom Candyce Hubbell has the same secret — and she hides it from her pediatrician. "I don't really want to be lectured," she says. "I know what her stance will be on it."

This story was originally published in May 2018.

There's no other way to put it: Maria de los Angeles Tun Burgos is a supermom.

She's raising five children, does housework and chores — we're talking about fresh tortillas every day made from stone-ground corn — and she helps with the family's business in their small village about 2 1/2 hours west of Cancún on the Yucatán Peninsula.

A hundred years ago, the world was struck by a nightmare scenario.

World War I was still raging. And then a suspicious disease appeared.

Scratch another Guinea worm hot spot off the list.

One of the countries hardest hit with the parasite — South Sudan — has finally stopped transmission, the Carter Center announced Wednesday.

The country reported zero cases in 2017 and hasn't had a case in 15 months. There are also no signs Guinea worm is circulating in dogs in South Sudan, as it is in Chad and Mali.

If you want to cut your risk of catching the flu on your next flight, pick a window seat and stay put.

That's a key take-home message of a study published Monday in the Proceedings of the National Academy of Sciences.

To see if you're bending correctly, try a simple experiment.

"Stand up and put your hands on your waist," says Jean Couch, who has been helping people get out of back pain for 25 years at her studio in Palo Alto, Calif.

"Now imagine I've dropped a feather in front of your feet and asked to pick it up," Couch says. "Usually everybody immediately moves their heads and looks down."

Earlier this week, we shared the remarkable story of Abby Beckley — and her run-in with eye worms.

When this young woman felt something crawling around in her eyes, she had the presence to remove said worm and then, over the course of a few weeks, not one, not two nor three ... but 14 nematodes came out from her eye.

At first doctors didn't believe her. Then they saw one squiggle across her eyeball.

On Christmas Day last year, a 68-year-old woman in southern China came down with the flu. A week later she was hospitalized.

The woman eventually recovered, but she spent three weeks in the hospital.

The culprit? H7N4, a new type of bird flu.

"This is the first case of human infection with avian influenza A (H7N4) in the world," the Hong Kong Centre for Health Protection said Wednesday in a statement.

Oh my lordy! This story gets creepier and crazier the more you learn about it.

Back in the summer of 2016, Abby Beckley had been living on an inactive cattle ranch in southern Oregon. "There was just one cow," says the 28-year-old college student.

A few weeks later, she started to have the sensation that something was in her eye. "You know how it feels when you have an eyelash in your eye?" Beckley says. "That's exactly how it felt, but when I looked in the mirror, I couldn't see anything."

There's a glaring hole in President Trump's budget proposal for 2019, global health researchers say. A U.S. program to help other countries beef up their ability to detect pathogens around the world will lose a significant portion of its funding.

The ambitious program, called Global Health Security Agenda, was launched in early 2014, aiming to set up an early-warning system for infectious diseases across the world.

If the Russian psychologist Ivan Pavlov were alive today, what would he say about smartphones? He might not think of them as phones at all, but instead as remarkable tools for understanding how technology can manipulate our brains.
