Like many other fungi, coccidioides species have a complex life cycle. In the soil, they grow as a mold with long filaments that break off into airborne spores when the soil is disturbed. A person can then inhale the spores. The spores are extremely small and can be carried far by the wind.
Once inside the lungs, the spores reproduce, continuing the disease cycle. Environmental exposure. Anyone who inhales the spores that cause valley fever is at risk of infection. People who live in areas where the fungi are common—especially those who spend a lot of time outdoors — have a greater risk. Also, people who have jobs that expose them to dust are most at risk — construction, road and agricultural workers, ranchers, archaeologists, and military personnel on field exercises.
