Valley Fever - Determination of Geological/Ecological Occurrence Models for Coccidioides ImmitisFor additional information, please visit http://esp.cr.usgs.gov/info/sw/cimmitis.html. Valley fever (Coccidioidomycosis) is an infection caused by inhalation of the spores (arthroconidia) of a soil-inhabiting fungus, Coccidioides Immitis. The disease is a public health issue of great importance in the deserts of the southwestern U.S. as a result of rapid population growth, increased outdoor recreational activities, and placement of military personnel for active training. These demographic changes place an increasingly large, previously unexposed population within endemic areas. These conditions, coupled with increasing numbers of individuals with suppressed immune systems, are a National concern. When an area has been mapped for occurrences of C. immitis, investigators will begin monitoring this area for potential dust emissions and transport pathways that might affect human populations.
