Avenal in California's central valley is at the centre of the valley fever epidemic.

You're never rid of it, says Mary Garcia, a resident of Avenal.

"There are times I wake up and I'm in a lot of pain. It's like the worst fever you've ever had from a flu," she adds.

She caught valley fever 10 years ago, and sometimes, when the wind blows, it returns.

If any of her children get it, she says she will move away.
