About

- Valley fever (coccidioidomycosis) is
a fungal infection.
It lives in the soil in the southwestern U.S., parts of Washington state, and Central and South America.- Non-contagious:
It does not spread from person to person but is contracted by inhaling
fungal spores from the environment.
- Most cases are mild, with either no
symptoms or flu-like symptoms that resolve on their own.
- However, in rare cases, it can cause
serious health complications or ongoing lung problems.
- Chronic pulmonary coccidioidomycosis may
lead to additional symptoms:

Causes
- Valley fever is caused by inhaling
fungal spores from the Coccidioides species, which can
grow into clusters in the lungs and spread throughout the body.
- Two species of fungi can cause the
infection.
- Coccidioides immitis:
Found in California.
- Coccidioides posadasii:

air by disturbing the soil during construction, dust storms, or farming
activities.
