Ebola Virus in Zaire

ebola virus



Beginning with the January 1995 outbreak of Ebola virus in Kikwit, Zaire, the CHAART staff have been working with investigators from the Special Pathogens Branch at the Centers for Disease Control and Prevention (CDC) in Atlanta to generate images of the area where the first Ebola cases were found. The investigation in Kikwit was initially hampered to a great extent by the lack of accurate and up-to-date maps. The CDC team expressed a need to (1) accurately identify the location of exposure and residence of human patients, (2) geographically reference the collection of vertebrate and invertebrate materials from the ecological investigation, and (3) correlate these collections with underlying landscape and faunal characteristics. The long-term goals of the collaboration are to use remotely sensed environmental information to supplement observations of the basic ecology of the field sites, and to utilize a geographic information system to relate these data with other epidemiological information to investigate the temporal and spatial elements of the outbreak. As part of this collaboration, CHAART scientists have provided the CDC team with several image products, generated from archived SPOT multispectral data and current Landsat Thematic Mapper data. Vegetation indices, as well as landcover classifications, have been created from these spectral datasets, making it possible for the CDC team to georeference field data and estimate vegetation changes in the area since 1985.
