COCCIDIOIDOMYCOSIS (VALLEY FEVER)
Coccidioidomycosis or Valley Fever is an infectious disease in parts of the U.S.A. It is caused by inhaling microscopic arthroconidia (also known as arthrospores or spores) of the closely related fungal species Coccidioides immitis and C. posadasii. Areas where Coccidioides is endemic (native and common) include states in the southwestern U.S.A. such as Arizona, California, New Mexico, Nevada, Texas, and Utah and parts of Mexico, Central America and South America.
The purpose of this website is to provide occupational safety and health professionals with information needed to understand and prevent work-related Coccidioidomycosis (Valley Fever). The disease has important occupational aspects. For example, certain jobs and work activities, particularly those that involve digging in or disturbing soil in endemic areas, are associated with an increased risk of infection to workers. Also, it is important to know that there are preventive interventions that can be used to protect workers at risk.
