The first phase of fighting the Ebola Virus Disease in West Africa was an enormous success but harder challenges lie ahead, according to a Swedish professor working with the Liberian Ministry of Health.

Hans Rosling says he spent 20 years studying epidemics, and when the Ebola outbreak hit he immediately asked how he could assist.

So far, 5000 people have died from Ebola in Liberia, Guinea and Sierra Leone.

Professor Rosling arrived two weeks ago, and plans on staying until the situation improves.

Eva Flomo asked him about his initial assessment of the situation on the ground.
