The number of people who are infected with the new coronavirus that is spreading from China is dwarfed by those affected by a far more common respiratory illness: seasonal flu.

Every year there are as many as 5 million severe flu cases worldwide and hundreds of thousands of deaths. By contrast, so far there have been about 20,000 (and rising) cases of coronavirus, most of them mild.

Just a few months ago, Tom Inglesby helped gather top officials from governments, businesses and health organizations around the world to play a kind of war game.

"It was a scenario looking at global consequences of a major new epidemic," says Inglesby, who directs the Center for Health Security at Johns Hopkins University.

Last fall, Félix Tshisekedi, the president of Democratic Republic of Congo, made a triumphant prediction: Before 2019 was over, the Ebola outbreak that had ravaged his country for more than a year would finally be brought to a close. Already, health workers had managed to quash the Ebola virus in all but a small set of remaining hot zones. New infections had slowed to a trickle.

Dr. Marie-Roseline Bélizaire had just gathered the members of her Ebola response team for a morning meeting when they heard the rat-a-tat of gunfire.

As holiday donations kick off with this Giving Tuesday, we're going to bring up an aspect of contributing to charity that makes a lot of us ... uncomfortable.

We're talking about the idea that every time we divvy up our money among good causes, we're making a moral judgment: Who is most deserving of our help and which outcomes are most valuable?

Over the past decade there has been a surge of interest in a novel approach to helping the world's poor: Instead of giving them goods like food or services like job training, just hand out cash — with no strings attached. Now a major new study suggests that people who get the aid aren't the only ones who benefit.

In the United States, drugmakers have flooded the market with powerful, sophisticated opioids. And that's fueled an epidemic of addiction. But across Africa many patients can't afford even mild painkillers — let alone medications to help people in extreme pain.

Uganda has come up with a solution that goes back to basics with one of the world's original painkillers: morphine.

The work is dirty, dangerous ... and thankless.

Sanitation workers in lower income countries often endure grueling conditions to perform a service that's vital to keeping their communities healthy. Yet their suffering has largely gone ignored — even by advocates for the poor.

Almost as soon as the e-cigarette maker Juul launched in the Philippines this past June, Maria Encarnita Limpin started noticing the product in shops all over the capital Manila.

"It's like they mushroomed," she says.

Limpin is a doctor specializing in lung disease and also directs a nonprofit that has helped push though rules preventing the marketing and sale of cigarettes to minors in the Philippines. So she was particularly horrified to see how visible Juul's vaporizers are in areas where children are likely to see them.
