Develop a Valley Fever decision-support database 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 significant annual incidence, exceeding significantly other climate-related diseases (e.g., Hantavirus; West Nile Virus). We develop under the present agreement in collaboration with the Arizona Department of Health Services (ADHS) a public health decision-support database that builds on these findings. We have in Year 2 worked with ADHS to secure zip code level human case data for model validation; modeled exposure date; completed climate-satellite-derived data time series correlations; and performed initial multi-layer, multi-scale remote sensing based spatial analysis of soil structure and disturbance.. The database will serve as a practical reference for health officials and as a model for health information support systems in general.

Future Activities:

The overall aim of Year 3 is to finalize climate, surface moisture, ecological and exposure databases. We will articulate these databases with zip code and county level human cases so outcomes are useful potentially at both county and local scales. The zip code data provide a basis for fine scale studies we believe are key to understanding the operational scale of this pathogen. The fine scale work on fungal ecology and disturbance was neither proposed nor funded for the current effort. We have recruited graduate student researchers to expand the merits of this.
