The Ebola virus

Some 300 people died during the first documented outbreak of the deadly disease occurred in the 1970s in the Democratic Republic of Congo - then known as Zaire. The virus was named after the river which flowed close to the village where it was discovered. Two doctors, Dr Jean Jacques Muyembe and Dr David Heymann, were among those who worked to bring the outbreak under control. They spoke to Claire Bowes in 2009.
