FAQs
What are the symptoms of Valley fever?
Most people (60%) have no symptoms or only very mild flu-like symptoms and do not see a doctor. When symptoms are present, the most common are fatigue, cough, fever, profuse sweating at night, loss of appetite, chest pain, generalized muscle and joint aches particularly of the ankles and knees. There may also be a rash that resembles measles or hives but develops more often as tender red bumps on the shins or forearms.
How do I prevent getting Valley fever?
There is no prevention or vaccine at this time. Avoiding activities associated with dust and airborne dirt of native desert soil is recommended, but it is not a certain means of prevention, as the dust may or may not contain coccidioides spores. Some occupations recommend wearing masks. Use common sense and stay out of the blowing dust.
