Liberian government on high alert for Ebola

The Liberian government says it is on high alert to detect and treat any further cases of Ebola following the resurgence of the outbreak last week.

Liberia was declared Ebola free two months ago but the emergence of new cases has puzzled the Ebola response teams.

Tolbert Nyenswah, Liberia's Deputy Minister for Health, said the source was yet to be identified.
