Ebola outbreak: Scientists concern over virus mutation
Fewer than a 100 cases of the Ebola virus were confirmed in West Africa last week, according to the latest World Health Organisation (WHO) figures.
The number is the lowest recorded since June but scientists in France who are tracking the outbreak have said the virus could be mutating.
They have predicted there will be another Ebola outbreak but say they hope the work being done will mean it will not be as severe.
