FREETOWN, Sierra Leone - 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.
The Ebola outbreak is the largest in history with deaths blamed on the disease not only in Sierra Leone and Liberia, but also Guinea and Nigeria. The disease has no vaccine and no specific treatment, with a fatality rate of at least 60 percent.
Binyah Kesselly, chairman of the Liberia Airport Authority board, said police are now present at the airport in Monrovia to enforce screening of passengers.
