Online SARS map shows outbreak sites

Online SARS map shows worldwide cases

Corda Technologies Inc. of Lindon, Utah, has posted a map online that shows the number of severe acute respiratory syndrome (SARS) cases worldwide.

The site, at, shows the location of diagnosed cases of SARS. The online map uses Corda's OptiMap 5.0 and PopChart display software. Visitors can move a cursor over the map to read pop-up text about the number of cases in each country. The map of the United States offers a drill-down feature so visitors can view the number of cases suspected, probable or diagnosed in each state.

OptiMap pulls the data directly from a link at the World Health Organization Web site at, and from links at the Centers for Disease Control and Prevention Web site,

People with visual impairments also can access the site. Clicking on a tiny 'd' under the map takes the visitor to a text version of the graphic, which can be read by a screen reader.
