Where can you get Valley fever?
Most cases of Valley fever in California (over 65%) are reported from the Central Valley and Central Coast regions. People are more likely to get Valley fever if they live, work, or travel in these areas or travel to other places where Valley fever has been reported. There is no commercial test available to see if the Valley fever fungus is in the dirt or dust in certain areas, but we do know that Valley fever has been diagnosed in people living throughout California.
