University of Arizona Communications reports that a UA researcher has devised an ingenious way to demonstrate the relative level of vulnerability to bioterrorism in 132 U.S. cities. UA’s Walter W. Piegorsch has created a color-coded map that identifies the risk based on factors such as critical industries, ports, population, etc. The map highlights high-risk areas as red (for example, Houston), midrange risk as yellow (San Francisco) and lower risk as green (Tucson).

Thank you for your contribution to our collective security, Dr. Piegorsch.
