Stephen Albert Johnston, Krupa Navalkar and their colleagues at Arizona State University’s Biodesign Institute have been investigating valley fever. Navalkar is the lead author of a new study describing 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.
