Ebola crisis: Training exercises undertaken

The World Health Organisation says a treatment is being developed to tackle Ebola.

It will reportedly be a serum made from the blood of patients that have recovered from the disease in Liberia. The current outbreak of the virus has already killed more than 4,875 people - mostly in Guinea, Liberia and Sierra Leone.

Global Health correspondent Tulip Mazumdar reports from Freetown, Sierra Leone, on how volunteers are being trained to carry out safe burials.
