Coccidioidomycosis (/kɒkˌsɪdiɔɪdoʊmaɪˈkoʊsɪs/, kok-sid-ee-oy-doh-my-KOH-sis), commonly known as cocci, "valley fever", as well as "California fever", "desert rheumatism", and "San Joaquin Valley fever", is a mammalian fungal disease caused by Coccidioides immitis or Coccidioides posadasii. It is endemic in certain parts of Arizona, California, Nevada, New Mexico, Texas, Utah, and northern Mexico.
