- Abstract:
- This shapefile is part of the IGAD Minimum Medical GIS Database. GIS query of 1992-1995 annual composite maps of NDVI and Tmax for the IGAD zone of East Africa were compared to S. haematobium prevalence data from the WHO atlas on the distribution of schistosomiasis to statistically derive this model. The query (red area) shows NDVI values between 120-140 and Tmax values between 20-26. This is a preliminary model for S. haematobium. This model is based on thermal developmental requirements for S. haematobium, and adjustments are anticipated based on the concurrent requirements of the suitable Bulinus snail host species that occur in the region.
- Purpose:
- To be used as part of the IGAD Minimum Medical GIS Database. The extrapolation of the 'annual composite map' query to neighboring countries in the IGAD zone of East Africa provides an idea of where environments may be suitable for S. haematobium.

- 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 annual composite map by iteratively fitting query overlay areas to the spatial distribution of sites with >=5% prevalence. Query best-fit results were 120-140 NDVI and 20-26 Tmax. This result represents the annual composite model.
