EcoHealth Alliance has predicted the probable spread of Ebola via international flight routes.
The non-profit organisation, which examines global health issues, developed a set of global maps using available flight data.
It shows that the highest risk areas are the US and Europe. Countries most at risk include Germany, France and the UK, as well as Senegal, Ghana, Israel, the UAE and Japan.
EcoHealth Alliance used flight schedule data from Liberia, Guinea, Sierra Leone, Morocco, Nigeria and Ghana to calculate the risk of the disease spreading.
The organisation used its previous work identifying the pathways of the 2009 outbreak of Influenza A/H1N1 to form the basis of its plausible routes that Ebola infection could take.
