 Since the outbreak to call last March, there have been more than 20,000 confirmed author suspected cases of Ebola in Western Africa. More than 7,900 have been dealt with the vast majority of the cases in Liberia, in Guinea and Sierra Leone. World bank has slashed its economic growth estimate for those 3 countries it actually put the thing negative grow. For Guniea this year, it expects Sierra Leone's GDP to be down 2%, and Liberia are slightly more hopeful 3%. All significantly below precarious estimate and likely to cost the country billions of dollars. Join me now from a Washington bureau is David * a senior economist for the world bank Africa region. Here we thank you for being with us today. We have talked about some of those GDP statitics, but can you put this into summing terms for ? economic cost. Absolutely, thank you. The Ebola crisis obvious the first casualty is the actual human crisis has helped them suffering. But the economics scars have wield human states as well. What we are talking about is huge slashes in incomes with that mean in a country where you got a large chunk of the population. That's right around the poverty line, are big increases in poverty. Well this means our children who don't have food to eat. We recently talked to households in Liberia, more than 2/3 of the households in Liberia don't have enough food to eat as the result of the Ebola epidemic. We've seen the same kind of pattern in Sierra Leone. And in Liberia means mothers who normally take vegetables to the market to sell won't go because they are afraid of the explosure to the disease; and means fathers who were working in shop had been sent home because there's no bussiness. Really this is felt in every sector of the economy and throughout the country.
