Valley fever is an infection caused by fungi known as coccidioides. There are two species of coccidioides fungi that can lead to valley fever. These fungi are commonly found in soil within specific regions. Any disturbance to the soil, such as agricultural activities, construction, or wind, can release the fungi's spores into the air.

When people inhale these spores, they can develop valley fever, also known as acute coccidioidomycosis. Mild cases of the disease typically resolve without treatment. However, in more severe cases, healthcare professionals administer antifungal medications to treat the infection.

Types of valley fever

Valley fever, scientifically known as coccidioidomycosis, is a fungal infection caused by the fungus Coccidioides. This particular infection is most commonly found in individuals residing in dry and arid regions. There are two distinct forms of valley fever: acute and chronic.

Acute valley fever

Acute valley fever refers to the initial phase of the illness and is the most common type of valley fever. When individuals inhale fungal spores present in the air, they can become infected. The spores can settle in the lungs, leading to respiratory symptoms. The body's immune response may trigger symptoms such as fatigue, coughing, fever, headache, and muscle aches. In most cases, the acute form of valley fever resolves within a few weeks or months without medical intervention.

Chronic valley fever

Chronic Valley Fever is a more serious type of valley fever and occurs when the infection progresses beyond the acute phase and becomes a long-term condition. In certain cases, the fungal infection has the potential to disseminate to various body parts, such as the bones, joints, and central nervous system. This dissemination can result in more pronounced symptoms and potential complications. Chronic valley fever necessitates immediate medical attention and continuous treatment.

Disseminated coccidioidomycosis: It is a rare and severe form of the disease. It occurs when the infection extends beyond the lungs and spreads to other areas of the body. Typically, the infection affects the skin, bones, liver, brain, heart, and the membranes surrounding the brain and spinal cord (meninges).

Causes of valley fever

Valley fever is caused by inhaling fungal spores present in the soil. These spores are released into the air when the soil is disturbed, such as during construction, farming activities, or dust storms. Arid and dusty regions provide an ideal environment for the growth and dissemination of the Coccidioides fungus. 

Symptoms of valley fever

The symptoms of valley fever can differ based on the intensity of the infection. Mild instances of valley fever may not exhibit any symptoms. However, in more severe cases, the following symptoms can appear:

  • Fever
  • Cough
  • Fatigue
  • Shortness of breath
  • Chest pain
  • Headache
  • Muscle aches
  • Joint pain
  • Rash
  • Weight loss

Treatment Options for valley fever

The treatment for valley fever depends on the severity of the infection and the individual's overall health. In many cases, the acute form of the illness does not require specific treatment and resolves on its own. Medical professionals may recommend rest, hydration, and over-the-counter pain relievers to manage symptoms.

For individuals with chronic valley fever or severe symptoms, antifungal medications may be prescribed. These medications help eliminate the fungal infection and prevent it from spreading. The duration of treatment can vary, ranging from several months to a year or more. Regular follow-up visits with healthcare providers are essential to monitor progress and adjust the treatment plan if needed.

Prevention of valley fever

There is no vaccine to prevent valley fever. However, there are some things you can do to reduce your risk of getting valley fever:

  • Avoid areas where the fungus is found
  • Wear a mask when working in areas where the fungus is found
  • Wash your hands often
  • Avoid contact with people who have valley fever


Valley Fever is a complex illness that can have a significant impact on individuals living in affected regions. However, with awareness and education we can minimize the spread of this often misunderstood condition. If you reside in or visit regions where valley fever is prevalent, stay informed, and seek medical attention if you experience any symptoms. In most cases of valley fever go away on their own within a few weeks. If you have any concerns about valley fever, talk to your doctor.
