Authorities in Guinea are concerned about a new outbreak of cases just as officials hoped the crisis was coming under control.
The country where the Ebola epidemic began has recorded 27 new cases in a week, compared with seven the previous week, according to the World Health Organisation.
Health officials are particularly alarmed that some of the cases are in an area near the border with Guinea-Bissau, a deeply impoverished country with very few functioning health care centres.
Sakoba Keita, who heads Guinea’s anti-Ebola effort, said the country had been “close to victory” over Ebola, and the new cases mark a setback.
The Ebola epidemic began in Guinea in December 2013 and spread to neighbouring countries. Only Guinea and Sierra Leone are still reporting cases in west Africa.
