Abstract:

Objective To explore the drawing method of a statistical map based on statistics analysis system(SAS)and its application in the surveillance of exotic medical vectors and risk analysis in entry-exit inspection and quarantine system. Methods The statistical map method based on SAS program was applied for the classification statistics and data analysis of exotic medical vectors, with real-time, dynamic and automatic marking on the world map actualized. Results A world map was automatically drawn by computer and the related data and messages were labelled real-timely, dynamically and automatically on the world map in different colours. The locations of the twenty countries covered in this study were marked as asterisk in the map based on the longitude and latitude degree values of the capitals in those countries. Blue, yellow, orange and red colours were used to represent the different numerical levels of captured medical vectors. The numbers of vectors from Panama, Brazil and Thailand were marked by a blue asterisk indicating a relatively small number, while those from Korea South and South Africa were marked by red asterisk indicating a relatively large number. Conclusion The statistical map gives an intuitive, simple and dynamic illustration of the distribution of exotic medical vectors from different countries, contributing to inspection and quarantine authorities making timely, accurate and reasonable distribution of forces and strengthening quarantine supervision of what is imported from the countries as sources of relatively large number of exotic medical vectors.
