Nigeria has recorded its second Ebola case – that of one of the doctors who treated a man who died from the virus after his arrival from Liberia.
The health minister said a further eight people who came into contact with him have been placed in quarantine.
This year’s outbreak, the worst ever, has centred on Guinea, Liberia and Sierra Leone, killing 887 people.
New figures from the UN show that between July 31 and August 1, sixty-one deaths were reported.
Meanwhile, Liberia has ordered that the bodies of people killed by the Ebola virus must be cremated following the refusal of some communities to allow the burial of Ebola victims on their land.
