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.
Record summer heat has increased fire risk in California and the Western U.S. as drought conditions expand.
Statewide water conservation exceeded the mandatory goal in May and Sacramento reduced water use 40 percent.
In the fourth year of drought in California, sales and use of "safe and sane" fireworks are restricted in some areas, allowed in others.
A California Assembly committee will hear a bill Wednesday that would allow water districts to impose taxes on any business, industry or person who wastes water.
The drought can be blamed for a number of problems and the latest is a major decline in the duck population. A new survey shows lack of rain has led to poor habitats.
