The 42-day countdown to being declared Ebola free for a third time began on Thursday, Dec 3, after Liberia released last two known cases. The patients, a father and a younger brother of a 15-year-old boy who died on November 23, were discharged from a treatment unit (ETU) in the capital Monrovia....

The country was first declared free of human-to-human transmission in May, only to see the fever resurface six weeks later, and officially credited with beating the epidemic for a second time in September.

Speaking to state Radio, Tolbert Nyensuah, head of the country's Ebola response said,

     "As far as we know (there is) no case in the ETUs in the entire republic of Liberia,"

     "We also know that there is no new known transmission as of today, based on our epidemiological investigations." Nyesuah added.

Nyensuah said 165 potential contacts of the family -- 34 of them high-risk -- are going into the third week of the 21-day observation period, with none showing signs of illness.

Liberia was the last country affected by the Ebola outbreak, with Sierra Leone declared free of transmission in November and Guinea's last known case recovering two weeks ago.

The patients' recovery triggered a 42-day countdown -- twice the incubation period of the virus -- before Liberia can be declared free of transmission for a third time.

 

Ebola has left more than 11,300 people dead since December 2013 in its worst ever outbreak. Liberia has registered almost 10,700 cases and more than 4,800 deaths.

The World Health Organization said in an update on the outbreak on Wednesday that investigations into the origin of the latest cluster of cases were ongoing.
