Ebola: UK healthworkers explain motivation for volunteering

British health workers have attended a training session in London to prepare for travel to Ebola-affected countries.

Dr Amy Hughes explained how her passion for humanitarian work almost overrode her personal fear.

While nurse William Pooley told would-be volunteers about his experience of contracting the virus in Sierra Leone and his subsequent recovery.

Dr Catherine Houlihan said it was challenging working with Ebola patients in Africa but said, "You make a big difference".
