Sierra Leone's top Ebola doctor, Sheik Umar Khan Dies Sierra Leone's top Ebola doctor, Sheik Umar Khan, has died from the disease. He was infected earlier this month and died yesterday at a ward run by medical charity 'Doctors Without Borders' in the far north of the country. Sierra Leone's health minister, Miatta Kargbo described Khan as a national hero and praised his tremendous sacrifice in working to save the lives of others. His death comes days after Samuel Brisbane, a senior doctor at Liberia's largest hospital, died last Saturday at an Ebola treatment centre on the outskirts of Monrovia. Health workers are at serious risk of contracting the disease, which spreads through contact with bodily fluids. Meanwhile, Pan-African airline ASKY has suspended all flights to and from the capitals of Liberia and Sierra Leone over the worsening Ebola health crisis. Ebola described as the worst outbreak on record, has killed hundreds of people in West Africa. The World Health Organisation says 219 people in Liberia, 319 people in Guinea and 224 in Sierra Leone have died. ALJAZEERA
