| Abstract : Institut Penyelidikan Perubatan |
| Background: The application of the Geographic Information Systems (GIS) to the study of vector transmitted
diseases considerably improves the management of the information obtained from the field survey and facilitates
the study of the distribution patterns of the vector species.
Methods: As part of a study to assess remote sensing data as a tool for vector mapping, geographical features like
rivers, small streams, forest, roads and residential area were digitized from the satellite images and overlaid with
entomological data. Map of larval breeding habitats distribution and map of malaria transmission risk area were
developed using a combination of field data, satellite image analysis and GIS technique. All digital data in the GIS
were displayed in the WGS 1984 coordinate system. Six occasions of larval surveillance were also conducted to
determine the species of mosquitoes, their characteristics and the abundance of habitats.
Results: Larval survey studies showed that anopheline and culicine larvae were collected and mapped from 79
and 67 breeding sites respectively. Breeding habitats were located at 100-400 m from human settlement. Map of
villages with 400 m buffer zone visualizes that more than 80% of Anopheles maculatus s.s. immature habitats were
found within the buffer zone.
Conclusions: This study amplifies the need for a broadening of the GIS approach which is emphasized with the
aim of rejuvenating the dynamic aspect of entomological studies in Malaysia. In fact, the use of such basic GIS
platforms promote a more rational basis for strategic planning and management in the control of endemic
diseases at the national level. |
