According to a report, a teenage boy died of Ebola in Liberia less than three months after the country was declared free of the virus.
A 15-year-old boy has died of Ebola in Liberia less than three months after the country was declared free of the virus, officials have told the BBC.
Francis Kateh, the chief medical officer, said the boy 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.
The teenage boy's mother and two other siblings have also been admitted to the treatment centre to be monitored, health ministry spokesman Sorbor George said.
He told the BBC that eight healthcare workers "who are at high risk because they came in direct contact with the boy" were also under surveillance.
The BBC's Jonathan Paye-Layleh in Monrovia says nearly 160 people are now being monitored since the new cases were confirmed last week.
Radio and television stations have resumed broadcasting Ebola awareness messages, he says.
Liberia has seen more than 10,000 Ebola cases and more than 4,000 deaths since the West Africa outbreak began in 2013. The World Health Organization (WHO) has twice declared Liberia to be Ebola-free, once in May and again in September.
