Preventing Work-Related Valley Fever

Valley fever, also called Coccidioidomycosis or "cocci", is an illness caused by a fungus found in the soil in many parts of California, especially the Central Valley and Central Coast. For some, it can be serious and even fatal. People who inhale fungal spores released when the soil is disturbed, may get Valley fever. 

Construction workers and others who work outdoor are at risk for Valley fever, especially if they dig or disturb soil, operate heavy machinery, or work under windy conditions.

A new California law, AB 203, requires construction employers who work in counties with high rates of Valley fever to train their employees on minimizing the risk of Valley fever by May 1, 2020 and then annually .

The Occupational Health Branch (OHB) has investigated Valley fever outbreaks in worker groups and has developed recomendations for preventing work-related Valley fever.
