Filariasis in the Nile Delta
During 1995, NASA sponsored RS/GIS training at CHAART for Dr. Ali Nasser
Hassan, from Ain Shams University, Cairo, Egypt. Dr. Hassan's goal was to
use RS and GIS to explore the spatial patterns of filariasis cases in the
Nile Delta.
This disease is transmitted by the mosquito Culex pipiens, which is
frequently found in houses with cesspits in areas with a high water table.
Landsat Thematic Mapper data, which coincided with Dr. Hassan's epidemiologic
field data
(25K), were converted into vegetation and moisture indices, as well as
classified into landcover types. Statistical analyses were used to compare
these landcover variables with the spatial distribution of microfilaria in
201 villages, spread throughout
10 communities.
Dr. Hassan's results papers are listed on the
Bibliography page.
