WHO to declare Guinea Ebola free Guinea is to be declared free of Ebola by the World Health Organization WHO, two years after the epidemic began there. Guineans are expected to celebrate the landmark with concerts and fireworks. The disease killed more than two thousand 500 people in the country and a further nine thousand in Sierra Leone and Liberia. Sierra Leone was declared free of Ebola in November, but new cases have emerged in Liberia, which had been declared Ebola-free in September. A country is considered free of human-to-human transmission once two 21-day incubation period passes since the last known case tested negative for a second time. SOURCE: BBC News
