Server-based GIS for epidemic disease management

As air travel becomes more affordable today, increased overseas travel is also increasing instances of spread of infectious diseases that can endanger citizens at home and abroad. To assist epidemic control personnel, Centers for Disease Control, Taiwan has developed an epidemic situation management system to help avoid delay in any reporting of dengue disease and thereby controlling epidemics

With air travel becoming popular and affordable, the number of both foreign tourists and Republic of China citizens’ outbound travel has doubled. However, the increased overseas travel can also facilitate the spread of infectious diseases which can endanger citizens at home and abroad. To prevent such a scenario, Centers for Disease Control (CDC), Taiwan continually focuses on disease prevention, quarantine, and surveillance to meet the needs of disease control.

Situated in subtropical zone, dengue fever has gripped Taiwan in recent years. In order to take control of the epidemic throughout the country, the project aims to help CDC develop an epidemic situation management system by means of server GIS software, store information of the infected patients and locations where dengue fever occurred, understand the epidemic situation in each district and then clearly distinguish whether dengue is mainly caused by vector mosquito habitats.

The epidemic situation management GIS system enables the infection control personnel to report dengue fever anywhere after logging into the online system and consequently employ map display and diverse analysis functions to determine the mutual relations among dengue fever occurrence, locations and vector mosquito habitats.

GIS platform
In this project, SuperGIS Server 3.1 was utilised as the GIS platform core to distribute and manage map information and build map websites. The server GIS allows developers to apply customisation functions, Jquery and Javascript syntax to create their own map websites with interactive visual effects. Besides, the system adopts Microsoft SQL Server 2008 as the database management software to manage spatial-related indices and statistic information for efficient data querying.

Serving to integrate infectious disease cases with the location where the diseases occurred, the Epidemic Situation Management GIS System enables relevant departmental executives to access the information about controlled area of mosquito habitats, vector mosquito indices, position of public location, etc; while utilising the accurate references to formulate disease prevention plans to combat the threat of communicable diseases and safeguard the life and health of the citizens.
