Sierra Leone’s top Ebola doctor, Sheik Umar Khan, has died after treating more than 100 patients as the horrific disease continues to spread with doctors fearing the world could be about to witness the worst outbreak in history. Health officials admitted they did not have all a list of everyone a Liberian patient came in contact with before dying from the disease, which means the outbreak could continue to grow rapidly.
The 2014 West Africa Ebola outbreak is already the deadliest in history, with 672 deaths from the disease, and at least 1,201 cases. Sierra Leone, Liberia, and Guinea have been the worst hit countries, but it has already spread, with Nigeria recently seeing its first death. Doctors fear if the disease spreads to the heavily populated Nigerian city of Lagos, the seventh-fastest growing city in the world, it could become out of control.
