![]() Valley fever is not a contagious disease.Ī skin lesion due to Coccidioides infectionĪn estimated 60% of people infected with the fungi responsible for coccidioidomycosis have minimal to no symptoms, while 40% will have a range of possible clinical symptoms. Disseminated coccidioidomycosis, which includes primary cutaneous coccidioidomycosis.Acute coccidioidomycosis, sometimes described in literature as primary pulmonary coccidioidomycosis.Therefore, coccidioidomycosis may be divided into the following types: Valley fever may progress to the chronic form and then to disseminated coccidioidomycosis. ![]() Classification Īfter Coccidioides infection, coccidioidomycosis begins with Valley fever, which is its initial acute form. It was reported in 2022 that valley fever had been increasing in California's Central Valley for years (1,000 cases in Kern county in 2014, 3,000 in 2021) experts said that cases could rise across the American west as the climate makes the landscape drier and hotter. In some cases the infection may recur or become chronic. Infections usually occur due to inhalation of the arthroconidial spores after soil disruption. Ĭoccidioidomycosis is a common cause of community-acquired pneumonia in the endemic areas of the United States. 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. Windstorms may also cause epidemics far from endemic areas. 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. immitis is dormant during long dry spells, then develops as a mold with long filaments that break off into airborne spores when it rains. It is also commonly found in northern Mexico, and parts of Central and South America. It resides in the soil in certain parts of the southwestern United States, most notably in California and Arizona. immitis is a dimorphic saprophytic fungus that grows as a mycelium in the soil and produces a spherule form in the host organism. Coccidioidomycosis is endemic in certain parts of the United States in Arizona, California, Nevada, New Mexico, Texas, Utah, and northern Mexico.
