Treatment
Significant disease develops in fewer than 5% of those infected and typically occurs in those with a weakened immune system. Mild asymptomatic cases often do not require any treatment. Those with severe symptoms may benefit from antifungal therapy, which requires 3–6 months or more of treatment depending on the response to the treatment. There is a lack of prospective studies that examine optimal antifungal therapy for coccidioidomycosis.On the whole, oral fluconazole and intravenous amphotericin B are used in progressive or disseminated disease, or in immunocompromised individuals. Amphotericin B was originally the only available treatment, but alternatives, including itraconazole and ketoconazole, became available for milder disease. Fluconazole is the preferred medication for coccidioidal meningitis, due to its penetration into CSF. Intrathecal or intraventricular amphotericin B therapy is used if infection persists after fluconazole treatment. Itraconazole is used for cases that involve treatment of infected persons bones and joints. The antifungal medications posaconazole and voriconazole have also been used to treat coccidioidomycosis. Because the symptoms of coccidioidomycosis are similar to the common flu, pneumonia, and other respiratory diseases, it is important for public health professionals to be aware of the rise of coccidioidomycosis and the specifics of diagnosis. Greyhound dogs often get coccidioidomycosis; their treatment regimen involves 6–12 months of ketoconazole taken with food.A particular severe case of meningitis caused by valley fever initially received several incorrect diagnoses such as sinus infections and cluster headaches. The patient became unable to work during diagnosis and original search for treatments.
Coccidioidomycosis (, kok-SID-ee-oy-doh-my-KOH-sis), commonly known as cocci, Valley fever, as well as California fever, desert rheumatism, or San Joaquin Valley fever, is a mammalian fungal disease caused by Coccidioides immitis or Coccidioides posadasii. Coccidioidomycosis is endemic in certain parts of the United States in Arizona, California, Nevada, New Mexico, Texas, Utah, and northern Mexico.C. immitis is a dimorphic saprophytic fungus that grows as a mycelium in the soil and produces a spherule form in the host organism. It resides in the soil in certain parts of the southwestern United States, most notably in California and Arizona. It is also commonly found in northern Mexico, and parts of Central and South America. C. immitis is dormant during long dry spells, then develops as a mold with long filaments that break off into airborne spores when it rains. The spores, known as arthroconidia, are swept into the air by disruption of the soil, such as during construction, farming, low-wind or singular dust events, or an earthquake. Windstorms may also cause epidemics far from endemic areas. In December 1977, a windstorm in an endemic area around Arvin, California led to several hundred cases, including deaths, in non-endemic areas hundreds of miles away.Coccidioidomycosis is a common cause of community-acquired pneumonia in the endemic areas of the United States. Infections usually occur due to inhalation of the arthroconidial spores after soil disruption. The disease is not contagious. In some cases the infection may recur or become chronic.
