A leading doctor who risked his own life to treat dozens of Ebola patients died Tuesday from the disease, officials said, as a major regional airline announced it was suspending flights to the cities hardest hit by an outbreak that has killed more than 670 people.
Dr. Sheik Humarr Khan, who was praised as a national hero for treating the disease in Sierra Leone, was confirmed dead by health ministry officials there. He had been hospitalized in quarantine.
Health workers have been especially vulnerable to contracting Ebola, which is spread through bodily fluids such as saliva, sweat, blood and urine. Two American health workers are currently hospitalized with Ebola in neighboring Liberia.
