BREAKING:Sierra Leone's Top Ebola Doctor dies after contracting virus

Dailymail; U.K (29/07/14):

Sierra Leone's top doctor fighting an outbreak of Ebola has died from the virus, the country's chief medical officer, Brima Kargbo, said on Tuesday.

 Sheik Umar Khan, who was credited with 

treating more than 100 patients, was infected with Ebola this month and had been moved to a treatment ward run by medical charity Medecins Sans Frontieres in the far north of the country.

The news of his death comes as health officials admit they do not have a list of all the people a Liberian Ebola victim came into contact with in the hours before he collapsed, prompting fears the outbreak could spread.
