Revision 3 (28 June 2003)
On 29 March 2003, Dr Carlo Urbani, an expert on communicable diseases, died of Severe Acute Respiratory Syndrome (SARS). Dr Urbani was the first World Health Organization (WHO) officer to identify the outbreak of this new disease, in an American businessman who had been admitted to a hospital in Hanoi, Vietnam. Because of his early detection of SARS, global surveillance was heightened and many new cases have been identified and isolated before they infected hospital staff.

This map is a digital recreation of Dr Snow’s hand-drawn map. The 1854 cholera deaths are displayed as small black circles. The gray polygon represents the former burial plot of plague victims. The Broad Street pump (shown in the centre of the map) proved to be the source of contaminated water, just as Snow had hypothesised.

Corda’s world map of SARS displays data for each country affected by SARS. As the mouse moves over a country, a ToolTip appears with the cumulative number of reported cases. An accompanying graph shows SARS deaths by country. Users can also drill-down into the United States map to view how many cases have been reported in each state.

One of MapAsia’s SARS distribution maps for Hong Kong (24 April 2003). Legend: orange circle buffers: some other case(s) within 250m; yellow circle buffers: no other case within 250m; red triangle: infected case; purple triangle: de-listed case; green: suspected case (none shown in this screenshot). The toolbar to the left of the map provides the sort of functionality found in a standard desktop GIS interface.

MapAsia’s provincial SARS distribution map of China shown above adopts a dichromatic choropleth scheme with graduated provincial pie charts depicting the relative numbers of discharged/under treatment/ dead cases in affected provinces.
ESRI China’s “SARS GIS”—SARS case distribution in Hong Kong. Note the list of affected building addresses (bottom left).

The only infected building (Wing Shui House—red dot) seen in this screenshot falls within a public housing area (yellow).
