The last four cases of Ebola in Liberia were discharged from a treatment clinic in Monrovia, capital of the country, on Monday.
With their release from the hospital, the country is once again free of any known case of the virus, which re-emerged a month after the World Health Organisation (WHO) certified it free of Ebola.
Six cases were recorded in a fresh outbreak of the virus in Margibi County just outside Monrovia. Two have since died.
More than 11,200 people have died from Ebola since an epidemic broke out in December 2013 in neighbouring Guinea.
Sierra Leone and Guinea are yet to recover from the disesase.
