As the deadly virus claims its first victim in Nigeria, Africa's most populous country which has close links with the UK, experts warn British doctors to look for the signs

On Friday, a Liberian man who had travelled to the Nigerian capital Lagos died for the disease, heightening concerns international air travel could speed up its spread.
