British troops and a Royal Navy hospital ship are to be deployed to Sierra Leone on a mission to help fight the ebola outbreak in West Africa.

So far there've been 8-thousand recorded cases of the virus - with 4-thousand deaths.

Meanwhile, a Spanish nurse says she may have caught ebola by touching her face with protective gloves after treating a patient with the disease.

Dr Chris Dye from the World Health Organisation says the epidemic is far from under control.
