Talking to a doctor about Valley fever

en EspaƱol sa Tagalog



    Note: The symptoms of Valley fever are similar to other respiratory diseases, including COVID-19 and flu. Laboratory tests are needed to know whether symptoms are caused by Valley fever (which is caused by a fungus) or COVID-19 or flu (caused by viruses). Talk to a healthcare provider about testing to learn if symptoms could be Valley fever or another illness.


Talking to a Doctor about Valley Fever

If you have questions about Valley fever or think you may have it, be sure to talk to a doctor or healthcare provider. 

Valley fever symptoms can take 1 to 3 weeks to appear after breathing in the fungus from dust in outdoor air. These symptoms can often be mistaken for other illnesses and will likely last several weeks. The only way to find out if you have Valley fever is to see a doctor.

Before you talk to a doctor about Valley fever, think about any recent outdoor exposures to dirt and dust you may have had, especially if you work outdoors or have recently traveled to or through areas where Valley fever is common, including the Central Valley or Central Coast of California, as well as Arizona.


When you talk to a doctor or healthcare provider,
tell them if:


  • You have had any of the following symptoms for more than a week: cough, difficulty breathing, fatigue, fever, chest pain, night sweats, muscle or joint pain, rash, headaches, or unexplained weight loss

  • You have traveled to or through certain areas where Valley fever is common

  • You work outdoors in dusty areas or around worksites where dirt and dust is stirred up (for example, on construction or excavation sites)
