Nearly 1,000 people in Sierra Leone have been put under quarantine following the death of a 67-year-old woman who tested positive to Ebola.
It comes five days into a six-week countdown for the country to be officially declared Ebola-free.
The quarantine will last for three weeks, provided no new cases are recorded. More than 11,000 people have died since the start of the Ebola outbreak in Sierra Leone, Guinea and Liberia.
The BBC’s Umaru Fofana in the capital, Freetown, says the authorities had been optimistic after a long period without any new Ebola cases and this caught them off-guard.
Our correspondent says the quarantine is stricter than previous ones. It includes a curfew in which people will not be allowed to move from one house to another. Soldiers and police have been deployed to keep the quarantine in Sellakaffta, a village in Kambia on the northern border with Guinea.
