Officials detect disease in SellaKaffta, Kambia
A village in Sierra Leone has been put under quarantine following the death of a 67-year-old woman who tested positive for Ebola.
Officials detected the disease in SellaKaffta in the northern district of Kambia, just five days into a six-week countdown to the country officially being declared ebola-free.
A BBC correspondent said that authorities had been optimistic following a lengthy period without any new ebola cases and the finding had caught them off-guard.
He added that the quarantine is stricter than previous ones and includes a curfew in which people are not allowed to move from house to house.
Over 11,000 individuals have died in Sierra Leone, Liberia and Guinea since the Ebola outbreak begun.
Together with Sierra Leone's health ministry, the World Health organisation are planning a vaccination programme for those who may have come into contact with the woman.
Provided that no new cases are recorded, the quarantine will last three weeks and covers almost 1,000 people.
