Sierra Leone is holding a country-wide experiment: For three days, no one is allowed to leave their home.
It's part of the country's strategy for controlling the deadly Ebola virus. While people across Sierra Leone stay at home, teams of workers go door-to-door, educating the public about the disease.
The effort got its shaky start on Friday.
The streets were empty in the heart of Freetown, the capitol. The only sound came from a few street sweepers and a police van blasting a song from an old speaker.
