New wheat disease could spread faster than expected
Date:3/25/2009

pe and Asia, carried by migrating birds. From an initial source of infection in New York City in 1999, the West Nile Virus spread across most of North America within three years, and soon thereafter to the entire Western Hemisphere.

The spread of these diseases seems to follow very definable mathematical formulas, researchers found.

"It was surprising to see how closely the spread of very different plant, animal and human diseases followed the same mathematical relationship," Mundt said. "This is giving us a better ability to predict how various types of diseases may move, and hopefully prepare for them."

Though rapid transportation systems have become increasingly important in establishing new pathogens around the globe, Mundt said, most disease spread is still done by natural mechanisms once a disease is established, not people getting off a jet aircraft.
