How to cut child mortality in half… again

When Paul Allen and I started Microsoft, we had an ambitious goal: to put a computer on every desk and in every home. A lot of people thought we were out of our minds. But we believed in the power and potential of these machines to change the world. So every day, we came to work determined to make it happen. Now, it’s hard to imagine the world any other way. In a few short decades, that goal became reality for billions.

In 1990, the possibility that the world would be able to cut child mortality in half over the next thirty years would have seemed just as remote. But that’s exactly what happened. And I believe the world can do it again by 2040—we can cut child mortality in half once more—and get even closer to ending all preventable child deaths.

My introduction to this issue came 27 years ago, when I read a piece in The New York Times about deadly drinking water in the world’s poorest countries that contained the following statistic: “Diarrhea kills some 3.1 million people annually, almost all of them children.” Learning that shocked me to my core. There’s no greater pain than the death of a child. The death of millions of them—from something easily treatable in much of the world—is tragedy after tragedy on an almost unfathomable scale.

Before long, I was learning everything I could about global health generally and child mortality specifically. And shortly after, the Gates Foundation, which was just getting off the ground, made it our mission to fight preventable health disparities like this around the world—with an emphasis on children whose lives were being cut short before they ever had a chance.
