Professor Cameron Simmons told Bloomberg TV that there were several barriers stopping the spread of Ebola beyond West Africa.

He said that the disease usually begins and spreads among poor rural communities, who are unlikely to undertake international travel. Also, people who have Ebola will usually be too sick to travel. Thirdly, unlike influenza, which can spread through the air, Ebola is only spread through bodily fluids.

Cameron Simmons is a Professor in the Nossal Institute of Global Health and the Department of Microbiology and Immunology, at the University of Melbourne, as well as Professor of Infectious Diseases, Nuffield Department of Clinical Medicine, University of Oxford.
