Valley Fever often misdiagnosed

Valley Fever causes symptoms such as coughing, chest pain, fever, weight loss and night sweats--symptoms caused by many different kinds of pneumonia.

“In the office, a doctor isn’t able to tell what kind of pneumonia you have--whether it’s Valley Fever, or a bacterial pneumonia or a viral pneumonia--unless specific tests are done,” says Dr. John Galgiani, director of the Valley Fever Center for Excellence at the University of Arizona.

“Unless a doctor decides to do those tests, they may just assume it’s a bacterial infection (and) treat for that. As it turns out, in our part of the country, a third of those people actually have a fungal infection, not a bacterial infection ... so, the treatments really don’t help, because they aren’t therapeutic for a fungal infection.”

A simple blood test can help diagnose Valley Fever, Galgiani says, but up to 90 percent of doctors don’t order the tests.

Aside from the high rate of misdiagnosis, the fungal infection usually isn’t bad enough to require medicine. Two out of three cases aren’t severe enough to require medical attention and many people may never even know they’ve been infected, says Galgiani.

There is a one in 30 chance of contracting Valley Fever for each person in our community who has not yet had it, he says.

In rare cases, however, Valley Fever can cause serious illness and even be fatal. Tucker Peck knows firsthand what it’s like to have Valley Fever and be treated for something else.

The 28-year-old graduate student in the University of Arizona’s Clinical Psychology Program moved to Tucson 2 ½ years ago and that’s when his troubles began. After a series of both positive and negative tests for Valley Fever, his condition began to deteriorate after being prescribed the incorrect course of drug treatment.

“Over the summer, starting in June, I started getting pneumonia like twice a month,” says Peck, who was living in Seattle over that summer. He was forced to quit his job and doctors then prescribed steroids for asthma, which turned out not to be the problem.

“For asthma, you want to turn the immune system down, but with Valley Fever you want to turn it up," he says. "I’ve heard that’s pretty common for people to get misdiagnosed and get wrong medicines that make it worse.”

Peck says being treated for the wrong illness has given him health problems he’ll face for the rest of his life. After being treated with the incorrect medicine, Peck developed a grapefruit-sized abscess on his right lung.

“On September 10th, the abscess exploded. It’s a grapefruit’s worth of Valley Fever fungus shot all throughout my lungs, my chest, my airways,” says Peck. He was hospitalized for 18 days and had to have a piece of his lung removed and the rest of the organ cleaned.

Peck says he feels fine now, but worries the Valley Fever can come back at any moment, much like a person who has cancer in remission.
