Valley Fever Symptoms


Have no symptoms at all…

or the symptoms are so mild that they do not go to a healthcare provider. A person may develop a slight cold, which quickly goes away, giving the person the impression that they just had a “cold”.


Develop an illness severe enough to prompt the person to go to a healthcare provider.

The most common symptoms are described as flu-like.  They include cough, fever, headache, chills, sweats, chest pain, and feeling extra tired. Other symptoms that occur with Valley Fever include rashes (erythema nodosum and erythema multiforme) on lower legs and joint pain similar to arthiritis. The severity of the symptoms is probably related to the number of spores that humans or animals inhale.  The more spores that are inhaled, the worse the disease may be.   Symptoms typically develop between 7 and 20 days after the spores enter your body.

When chest x-rays are performed on persons with Valley Fever they typically show fluid in the one or both lungs (pneumonia/infliltrates), glands (hilar lymph nodes) behind the lungs become enlarged, or fluid built up around the lungs (pleural effusion).


Of the Valley Fever cases have the fungus leave the main site (lungs) and spread to other parts of the body.

When the fungus spreads beyond the lungs the case is said to be disseminated. Disseminated disease is very serious and usually occurs early after the initial infection. The disseminated sites where the fungus has been found include the skin, bones, lining of the brain and spinal cord, lymph nodes, spleen, liver, kidneys, or possibly any part of the body.  The signs and symptoms for disseminate disease depend on the location of spread.
