Liberia’s Health Ministry on Friday confirmed three Ebola cases months after the country was declared by the World Health Organization as free of Ebola.

“It all started on Thursday, Nov. 19, when we received a report from one of our reference laboratories that a blood sample from a live patient tested positive for Ebola,” Health Minister Bernice Dahn told a news conference.

She said the patients and high risk contacts are in care at an Ebola Treatment Unit in Monrovia.

Earlier today, a UN official made known the case of a 10-year-old boy who lived in the Paynesville, a suburb east of the capital Monrovia.

The case represents a setback for Liberia, which has seen more than 10,600 cases and 4,808 Ebola deaths since it was first announced in March, 2014, according to U.N. World Health Organisation figures. The country was declared Ebola free on 3 September.

The virus has killed about 11,300 people in Guinea, Sierra Leone and Liberia, but Sierra Leone was declared free of the virus on Nov. 7 and Guinea has begun its countdown to the end of the virus.

The 42-day countdown to be declared Ebola-free starts when the last patient tests negative a second time, normally after a 48-hour gap following their first negative test.
