Liberia confirms first new Ebola case after 20 days clear

Liberia has confirmed a new case of Ebola, after a 20-day period where no new cases had been reported.

There had been hopes the country might soon be declared free of the disease, but a woman tested positive for Ebola on Friday in the capital, Monrovia.

The World Heath Organization requires 42 days to elapse from the last known case before a country can be declared free of the virus.

More than 4,000 people in Liberia have died from the disease.
