Cities Might Not Be As Prepared As They Think For A Bioterrorism Attack

Imagine that a small group of terrorists deliberately infect themselves with smallpox and then walk around London, spreading it to the populace. How much could the terrible disease proliferate before the world realized something was amiss?

This unsettling question is at the heart of new computer model showing how a bioterrorism attack in one city could quickly become the world's problem. Scientists started off with the hypothetical release of smallpox in London, New York, Paris and other major cities, then simulated how travelers would carry the virus to a host of other countries. Their conclusion: In the best-case scenario, smallpox could spread to two to four nations before doctors managed to diagnose it. Still ahead would lie the monumental task of quarantining the infected, distributing vaccines and tracing the source of the outbreak.
