Coccidioides immitis is a fungal disease that causes the fungal infection known as Valley Fever (coccidioidomycosis). This fungus lives in the soil, in dry areas with little rainfall and replicates in environments with high soil humidity. The incidence of valley fever is linked to climate changes due to the life cycle of the fungus and it is a dimorphic fungus. The fungus remains dormant in the soil and lives on dead organic matter until the soil dries out. When the soil dries it becomes a fungal spore (arthroconidia) with thin filaments which then break off and become airborne when the soil in which they are found is disturbed. Spores can also become airborne during strong winds and ground movement due to excavation, construction, and cultivation (CDC, 2014). People indirectly come into contact with the spore through inhalation. The spore reproduces in the lungs after the host becomes infected. This fungal infection is not a transmissible (contagious) disease because it cannot be spread from person to person (Bazzo, 2013). Twenty-five percent of primary valley fever infections manifest as community-acquired pneumonia usually within 1 to 3 weeks after onset. infected. About 60% of infected people do not show any symptoms of infection, 10% of them develop flu-like symptoms, 5% develop a skin lesion, meningitis, osteomyelitis and 15% develop pneumonia-like symptoms. There is a small percentage of cases of development of disseminated coccidioidomycosis in the body. Some common symptoms of valley fever are fever, cough, headache, muscle aches, chest discomfort, malaise, and tiredness. The signs and symptoms associated with Valley fever can last six months or longer in those who are not diagnosed early (CDC, 2009).
