- Abstract:
- This shapefile is part of the IGAD Minimum Medical GIS Database. GIS 'dry season model' query of B. pfeifferi in Ethiopia, using snail distribution records from Kloos et al.. Birrie et al., and the snail museum collections of the Danish Bilharziasis Laboratory. Snail distribution data corresponds closely to S. mansoni prevalence data in relation to a forecast model based on NDVI and Tmax data derived from the Advanced Very High Resolution Radiometer onboard the National Oceanic and Atmospheric Administration satellite series. The 'best fit' model included NDVI values from 125 to 145 and a Tmax data range of 10-32 C. This model included 92.3%, 90.4% and 94.6%, of the positive snail sample sites in GIS query overlay areas extracted from annual, dry season and wet season composite maps, respectively. For other sites in Africa, other NDVI and Tmax ranges may be more appropriate, depending on the species of snail present, a topic that will be examined in further studies.

- Process_Description:
- To develop optimum criteria ranges for the dry season, values for 5 km buffers around survey sites were extracted from the combined 2-year dry season composite map by iteratively fitting query overlay areas to the spatial distribution of sites with >=5% prevalence.
