Invasive Species IntroductionSimulation

Diseases that once resided in one region are now more likely to be carried throughout the world. The West Nile virus was first identified in 1937 in Africa. But in 1999 the first case appeared in the US, sickening and killing dozens.

It is currently estimated that the number of invasive species entering the US per year is in the thousands!
