Initially, doctors thought Edie Preller had pneumonia, then tuberculosis, or maybe bronchitis. They quarantined her and ran tests. Six months later they discovered that she had inhaled a deadly spore from a fungus that grows throughout the region. The spore caused a disease called valley fever, which spread from her lungs into her brain.
Preller had been an in-home health care worker, taking care of other people who were ill. Then, in her 50s, she ended up in a losing battle for her own life, spending her last three years in and out of a hospital.
