Wonder what state or country has been hit hardest by the salmonella outbreak or where the latest cases have been detected? You can find out on HealthMap, a public-health surveillance system that scours Internet news sites and other sources for real-time information on outbreaks of infectious disease, and then plots that data on a freely accessible world map.

 

The HealthMap software first collects information from various sources, including alerts from the World Health Organization, discussions on public-health listservs, and breaking news from thousands of websites in six different languages from around the world.
