Valley fever, historically found only in the Southwest, is spreading. It can have devastating consequences.
Doctors couldn’t figure out what was wrong with Devin Buckley.
It was February 2018, and the previously healthy 18-year-old found that he couldn’t walk to the bathroom without becoming winded. That was in addition to the rapid weight loss, stomach problems and extreme fatigue that seemed to come out of nowhere.
The campus health center at the University of Arizona in Tucson, where Buckley was enrolled as a freshman, had no answers. Neither did anyone at urgent care.

CBS KOVR 13 News coverage on ‘Weather conditions cause Valley fever fears to increase in Northern California with Stuart Cohen
Fears over Valley fever are ramping up as the California Department of Public Health warns our historically wet winter, followed by dry and dusty conditions could be the perfect storm for increased risk of contracting the virus.
Valley fever, also known as coccidioidomycosis, is a disease caused by a fungus that grows in the soil and dirt. Hotbed areas are typically the Central Valley, but Stuart Cohen, the co-director for the Center for Valley Fever, said an upward trend in temperatures in recent years is contributing to a rise in Sacramento and the Northern California region.

Drought raises concern about elevated risks of Valley fever
With dry conditions plaguing the western United States, UC Davis Health infectious disease experts are concerned about an increase in cases of Valley fever. The fungal infection primarily manifests as a respiratory illness and can cause fever, cough and fatigue.
Valley fever is caused by the fungus Coccidioides, microscopic spores which live in soil in the southwestern parts of the U.S., including California. When the ground is disturbed by wind, construction, farming or other movement, the spores become airborne. They can then be inhaled, infecting the lungs and other parts of the body via the bloodstream.
“The drought in California could play a big role in an escalation of cases of Valley fever,” said George Thompson, a UC Davis infectious diseases specialist and director of the UC Davis Center for Valley Fever. “Dry conditions cause Coccidioides to form into spores and when the wind blows, they become aerosolized, allowing them to be inhaled and infect people's lungs.”

Valley Fever cases in California continue to increase
A potentially deadly illness found in the soil and dusty winds of California's Central Valley is on the rise, state health officials say.
Documented cases of Valley Fever rose 11 percent in 2018 — a preliminary total of 7,886 cases compared to 7,090 cases for the same period in 2017, according to the California Department of Public Health. Health officials said final data for 2018 will be available in March.
Valley Fever (coccidioidomycosis) is an illness caused by a fungus found in the soil and dirt in the Central Valley. The fungus thrives in areas of low rainfall, high summer temperatures and moderate winter temperatures. The spores are carried by the wind in dust particles when the desert soil is disturbed.

The Rise of Valley Fever
Two years ago California saw more than 6000 cases of a serious and sometimes fatal airborne infection called Valley Fever. In 2017 that number jumped to more than 8000 cases. That figure will likely rise again this year in California, as well as Arizona, Nevada, New Mexico, Texas and Utah where the fungus that causes Valley Fever is found. If you live in one of those states, you may have had the infection, but didn’t know it. The symptoms are easily confused with pneumonia and it’s commonly misdiagnosed.
An Incurable Disease Is On The Rise In California, And Scientists Say Climate Change Could Cause It To Spread To Much Of The Western US
A fungus that thrives in dry soil and warm weather has caused a record number of infections in California. Experts fear climate change will cause it to spread across the western US.
For days Alyssa Gonzalez was bedridden with a fever, a sore throat, loss of appetite, shortness of breath, and a rash all over her body.
The 18-year-old went to the emergency room twice, but doctors couldn’t figure out what was wrong.
Eventually, Gonzalez felt good enough to work, but while taking a customer’s order at a Starbucks one morning this July, the California teen lost her eyesight. She stumbled to the back of the cafe, running into things along the way, and sat down until she could see again.

Surviving Valley Fever
Severe case highlights importance of awareness, expert care
For seven months beginning in the fall of 2010, Virginia Cappel’s medical condition was touch-and-go.
The series of events that would change her life began simply, with flu-like symptoms, which Virginia and her husband Niels initially thought was bronchitis. But about a month later, when they left their home in Davis, Calif., for a vacation in the Midwest, Niels began to notice more ominous signs: disruptions in Virginia’s speech, a slower gait and confusion, such as associating the wrong words with activities.
