Valley fever is an infection triggered by the Coccidiodes fungus. This fungus is typically present in soil and dust in certain parts of southwestern United States and parts of Central America, Mexico and South America.

The spores are likely to form in wet, warm soil after a period of heavy rainfall. The spores are stirred into the air by anything that disrupts the soil such as farming, wind and construction. An individual can acquire valley fever by inhaling these tiny, airborne fungal spores.

A fungal infection generally starts in the lungs. In rare instances, it can even spread to the entire body. Some might also develop a chronic form of valley fever. This simply means that the symptoms can occur recurrently for extended periods of time.

  • Bed rest
  • Increased intake of fluids
  • Over-the-counter pain medications such as acetaminophen and ibuprofen

Medication
