The president of Sierra Leone is calling on the world to send millions of dollars, hundreds of doctors and thousands of nurses to his nation to help fight what he calls "a tragedy unforeseen in modern times."
President Ernst Bai Koroma says, "Our people are dying." He's speaking by videoconference at a World Bank meeting on the Ebola epidemic.
He says children are being orphaned, doctors and nurses are dying, and Sierra Leone's health care system is overwhelmed.
Koroma says the world's response has been slower than the spread of the disease, and its spread will threaten people everywhere.
The presidents of Guinea and Liberia also made pleas for more aid to fight the virus that has killed more than 3,800 people in West Africa.
