More than a billion people in the world lack access to basic health care. It’s a hard truth that Raj Panjabi pointed to as he accepted the TED Prize in 2017 — globally, there’s a shortage of accredited health workers, and many people living in remote areas are all but cut off from care. There’s a proven way to making sure they get it: Train locals to serve as community health workers, giving them the skills to bridge between their neighbors and the health care system. Trained community health workers can extend health care to millions of people.
