Develop a Valley Fever decision-support system for Arizona. This objective has not changed.

Progress Summary:

Understanding the basis of environmentally-mediated infectious disease is central to the mission of the Environmental Protection Agency. Valley fever (coccidioidomycosis) is a disease endemic to arid regions in the Western Hemisphere, and is caused by the soil-dwelling fungi Coccidioides immitis and Coccidioides posadasii. Arizona is currently experiencing an epidemic with >5500 cases in 2006, exceeding significantly other climate-related diseases (e.g., Hantavirus; West Nile Virus). Up to 80 percent of the seasonal variability in Valley Fever is based on antecedent precipitation and atmospheric dust concentrations (Comrie, 2005, Comrie and Glueck, 2007). We developed under the present agreement in collaboration with the Arizona Department of Health Services (ADHS) a public health decision-support system that builds on these findings. In Year 1, we have worked with ADHS to secure human case data for model validation, developed initial climate-satellite-derived data correspondences, and performed initial multi-layer, multi-scale remote sensing based spatial analysis of the surface landscape. The database will serve as a practical reference for health officials and as a model for health information support systems in general.
