Researchers investigate new mechanism for predicting how diseases spread

ty or country. It was previously thought that the more people travel, the faster the wave spreads. Now, using this new mechanism, Brockmann has found that the wave actually reaches a maximum speed and then levels off.

"Since you always return home, you don't carry the disease to as many places as we assumed in previous models," he said. "This has been previously overlooked in mathematical epidemiology research."

Brockmann and his group hope to incorporate this new sort of model in realistic models of specific diseases, like the H1N1 influenza, and bioinvasions.

"We've shown this basic mechanism that wasn't known before," he said. "Now we need to see just how it impacts specific diseases."
