In some villages deep in the Democratic Republic of Congo, where bridges may just be felled trees and there are few roads or telephones, a growing network of solar-powered radios is doing double duty, NBC News reports.
The FM and high-frequency radios, brought in to warn of imminent extremist attacks from a group called the Lord's Resistance Army, also help keep tabs on Ebola outbreaks.
One in May left at least three people dead, but after the second death, radio operators started transmitting warnings, Catholic Relief Services said. They advised people on what to do when they encountered someone who was infected.
"If this project did not exist, people would literally be dying and nobody would know about it until it became a huge crisis. Or nobody would know about it ever," Driss Moumane told NBC News.
