Sheik Umar Khan (ca. 1975 – July 29, 2014) was the chief Sierra Leonean doctor attempting to curb the country's Ebola outbreak.

The virologist is credited with treating over 100 patients before succumbing to the virus himself. He was recognized as a "national hero" by Sierra Leone's Health Ministry.

Death

Khan died of Ebola on July 29, 2014, after he had been moved to a new ward run by Medecins Sans Frontieres. Sierra Leonean president Ernest Bai Koroma had been due to visit his treatment center the following week.
