EBOLA

A 15-year-old boy has died of Ebola in Liberia less than three months after the country was declared free of the virus.

He tested positive last week and died late on Monday at a treatment centre near the capital, Monrovia.

His father and brother are being treated for Ebola at the centre.

Liberia has seen more than 10,000 Ebola cases and more than 4,000 deaths since the West Africa outbreak began in 2013.

Eight healthcare workers "who are at high risk because they came in direct contact with the boy" were also under surveillance.

Nearly 160 people are now being monitored since the new cases were confirmed last week.

Liberia recorded its first Ebola case in March last year and analysts believe the latest cases are a serious set-back for the country.

Sierra Leone was declared free of Ebola on 7 November.

More than 11,000 people have died of the disease since December 2013, the vastmajority of them in Liberia, Guinea and Sierra Leone.
