The World Health Organisation (WHO) says Liberia is Ebola free.

Liberia joins Guinea and Sierra Leone, which earned the status last year.

The WHO says that this 'effectively puts an end to the world's worst outbreak of the disease'.

However, the organisation warns that even though all known chains of transmission of Ebola have been stopped in West Africa, "the job is not over, more flare-ups are expected and... strong surveillance and response systems will be critical in the months to come".

Liberia had been declared free of the disease in May 2015, but a new case was reported in June.

The country was again declared to be free of Ebola in September - but another new case was discovered in November.

In total, more than 11,000 died from Ebola in West Africa over the past two years.
