Model reveals quick spread of potential bioterrorism attacks
The Telegraph - 07/25/2013
Scientists at Northeastern University in Boston hypothetically released smallpox in London, New York, Paris, and other major cities, and then simulated it being carried by travellers to other countries.
They published their findings in Scientific Reports, saying they believe a deliberate smallpox infection would spread to up to four countries before doctors diagnosed it.
These maps show what they predict would be the effect of a smallpox release in London, with the top map showing how far the disease would have spread before authorities realise.
