Sierra Leone’s President Ernest Bai Koroma has widened a quarantine to include another one million people in an attempt to curb the spread of Ebola.
The northern districts of Port Loko and Bombali, and Moyamba in the south, will in effect be sealed off immediately.
Nearly 600 people have died of the virus in Sierra Leone where two eastern districts are already blockaded.
Meanwhile, US President Barack Obama has said the world needs to act faster to halt the West Africa Ebola outbreak.
“There is still a significant gap between where we are and where we need to be,” Mr. Obama told a high-level United Nations meeting on Ebola.
