Valley fever has been the focus of new research that describes a promising strategy known as immunosignaturing, which can provide clinicians with an accurate identification of valley fever, a potentially serious affliction that is often misdiagnosed. Valley fever is a fungal respiratory infection. It can be acquired when microscopic spores of the soil-dwelling fungus are inhaled. Two forms of the fungus exist, Coccidioides immitis and Coccidioides posadasii. They are endemic to regions of Arizona, New Mexico, California, Nevada, Utah, Texas and northern Mexico.
