Ebola outbreak: NHS staff volunteer to help

The World Health Organization has warned the number of people with the Ebola virus could reach 20,000 by November if swift action is not taken now.

It has also been revealed that 164 NHS staff have volunteered to be part of the UK's efforts to contain the Ebola crisis in West Africa, which has already killed around 2,800 people there.
