Liberia Declared Free of Ebola
The West African country of Liberia is officially free of Ebola, World Health Organization officials announced Saturday.
There have been no new cases reported in 42 days, which is the equivalent of two incubation periods for the devastating disease, health officials said.
Still, the damage wrought by the worst Ebola outbreak in history leaves “”a scar on the conscience of the world,” Liberian President Ellen Johnson Sirleaf told the Associated Press on Saturday.
WHO officials also noted they are not letting their guard down, since 18 new cases were reported this week in the two other countries hit hardest by the deadly virus — neighboring Sierra Leone and Guinea.
Still, that was the lowest number of cases reported in a week so far this year, according to the WHO.
At least 11,005 people have died since the Ebola outbreak in West Africa began more than a year ago, the WHO said.
