It's the season for colds and flus — and a newly identified respiratory disease, COVID-19.

To cut your risk of catching a respiratory illness on your next flight, experts offer two pieces of common-sense advice: Wash your hands frequently and keep a distance from people who are sick.

Where to sit to prevent getting sick

A 2018 study suggests that to minimize contact with other passengers, you should pick a window seat and stay put.

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.

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.

Recent studies have found that people carrying malaria release a signature scent. "So I thought, 'Well, if a dog can smell fruits and vegetables in luggage, could they smell malaria in a person?' " Lindsay says.

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.
