New research shows how official figures understate the U.S. pandemic: On any given day the number of infected people who are actively contagious is ten times that day's tally of new reported cases.

Six takeaways from discussions at the annual meeting of the World Health Organization's Executive Board.

One year ago on Thursday, China notified the World Health Organization that it had discovered a new coronavirus circulating in Wuhan. NPR discusses what happened after that.

A year ago today, the WHO first learned of a cluster of pneumonia cases in Wuhan, China of "unknown" origin. Here's the impact of that fateful day, by the numbers.

A new study suggests big sisters have a powerful impact. (Sorry, big brothers, you don't make as much of a difference.) But there are also potential downsides for the sisters.

A new study suggests kids in poor countries benefit hugely from having older sisters — who are more likely than brothers or even mothers — to engage in stimulating play.

It's part of an ongoing back-and-forth: Republican presidents ban U.S. funds for foreign aid groups that 'promote' abortion, Democratic presidents revoke the ban. This time things could be different.

Coronavirus cases are surging in many countries, including the United States and in Europe, and governments are imposing new lockdowns. NPR takes a look at the state of the pandemic around the world.

Steve Davis lays out the reasons for his (relatively) rosy outlook In his new book: Undercurrents: Channeling Outrage to Spark Practical Activism.

The authors of the "Global Burden of Disease" report track the toll from every conceivable cause of death or disability. This year they also share intriguing solutions that give cause for optimism.

The drug remdesivir emerged in part because researchers had previously tested it in China through a project whose grant was abruptly ended by the National Institutes of Health.

Nine months after the first reported fatality in China last January, the world has hit a sobering milestone.

The world is nearing a million deaths from COVID-19 — with almost every nation having lost people to the disease. And in the five countries hit badly by the pandemic, the trend remains worrisome.

The betterment of childhood vaccination rates has been a global success story. A new report on the impact of the pandemic offers reason for concern — and optimism.

The forecast comes from the University of Washington's Institute for Health Metrics and Evaluation. But here's why some other disease specialists are highly skeptical.

The results are in from a Nobel prize winner's landmark study of a deworming program. He finds the impact is immense. But the idea still gets mixed reviews

An inexpensive way to help kids in poor countries: hand out deworming pills so they're healthy enough to stay in school. A study by a Nobel Prize winner finds 20 years on, they earn higher wages too.

What's driving this death toll? Could anything improve the outlook? How reliable are these predictions anyway? We get into the weeds.

A team at the University of Washington's Institute for Health Metrics and Evaluation now projects the U.S. death toll from COVID-19 will reach nearly 300,000 by December.
