On Capital Public Radio's Insight, Rudolph pointed out that the lack of rain can dry out soils. That could increase dust levels, and dust carries pollen.
"[This] increases allergy and asthma. And dust can also carry pathogens. Over the last decade we've seen an increase in Valley Fever, a fungal disease in the Central Valley. That can be increased when dust levels increase and the spores of this disease are carried in the dust."

Rudolph says the drought could also trigger other health problems such as an increase in diabetes in some poor, rural communities. She says when drinking water becomes scarce, people turn to other fluids.
"And when those other alternatives are things like soda, it just exacerbates health problems such as obesity," she says.
Rudolph says droughts can also reduce agricultural crop yields leading to significant food price increases.
"And we see the same thing when people have to pay more for food. Low income people often turn to calorie dense food that is associated with more calories, obesity and diabetes," she says.
A long-range U.S. government forecast shows the drought in California will stick around.
The drought has farmers cutting back on watering, but some San Joaquin County growers say less water can mean a better crop.
The City of Sacramento Department of Utilities reports Friday that city water customers saved more than one-billion gallons of water last month.
California's economy will see modest growth in 2015, with jobs in home building being a bright spot, and the drought having slight impact, according to the latest University of the Pacific's latest Business Forecast.
It appears messages about the need for water conservation are beginning to get through to Californians.
