Two-thirds of all U.S. Valley Fever infections are contracted in Arizona even though nationally, Valley Fever is uncommon and considered an orphan disease. The Arizona Board of Regents established the Valley Fever Center for Excellence at the University of Arizona to improve understanding, medical care, and research about this disease.

Is Valley fever contagious?

NO! Valley fever is contracted only by the inhalation of the fungal spores. Valley Fever is NOT spread from human to human, or animal to animal, or animal to human or human to animal. The spores change form in tissues of the body and are not contagious in tissue form.

Who gets Valley fever?

Anyone who lives, visits, or travels through the areas where the fungus grows in the soil (these areas are called endemic) may acquire Valley Fever. People working in certain occupations such as construction, excavation, agricultural work, archaeological digging, or pursuing activities like biking or driving ATVs which disturb soil in endemic areas, may have an increased risk of exposure and disease. Earthquakes that have occurred in endemic areas of California have also resulted in increased cases of Valley fever. Various domestic animals such as dogs, cats, and horses as well as wild animals are also susceptible.

Does having Valley fever in the past make me more susceptible to contracting COVID-19?

There is no reason to believe that people who have had Valley fever are at higher risk for contracting COVID-19 as Valley fever does not interfere with or weaken a person’s immune system. (May 2020)

Is Valley fever contagious from animal to animal or animal to human?

Valley fever is considered a noncontagious disease. Even if multiple animals or humans are affected in a household, each infection was acquired by inhaling spores from the soil. Coughing cannot spread it between animals or people.
