A team of researchers has developed a dynamic mapping tool to gain a more nuanced view of the links between diseases and environmental exposures. The application of the method is illustrated by a number of examples of associations between environmental exposures and Salmonella infections among people in the US age 65 and over in 2002. Analysis of the dynamic maps revealed that Salmonella infections were more common during the summer months, were highly clustered in the South, and were potentially more common in areas with high broiler chicken sales. The study, published online in Environmental Health, features a set of principles the researchers developed to enhance the use of dynamic mapping technology in epidemiological research...
