Most people living in Arizona and around the southwestern United States are familiar with the fungal infection known as valley fever. It most commonly affects dogs, but all mammals are susceptible to the infection, including camelids like llamas and alpacas.

What Is Valley Fever?

Also called coccidioidomycosis, valley fever is a fungal infection caused by the coccidioides fungus which is found in soil regionally in the southwestern United States (especially south-central Arizona) and in parts of Central America and South America.
The term “valley fever” refers to both the fungal infection and the range of symptoms that it causes.

How Do Llamas and Alpacas Get Valley Fever?

Llamas and alpacas can contract valley fever the same way other mammals can, by breathing in infectious spores that are found in the soil. These spores can be kicked up from the dirt or can be breathed in while they are blowing around in dust in the wind.
Once the lungs have been exposed to the infectious fungal spores, the lifecycle of the coccidioides fungus continues. The spores take root in the lungs where they grow, mature, and reproduce. If left untreated, they can spread throughout a host’s body, causing painful symptoms and health problems throughout the body.

Signs and Symptoms of Valley Fever in Camelids

Initial signs of valley fever include:
If allowed to progress, disseminated valley fever will develop, causing the following symptoms:

Valley Fever Diagnosis and Treatment for Camelids

If your llamas or alpacas display signs and symptoms of valley fever, we strongly encourage you to schedule a veterinary examination. Prompt of valley fever is essential to preventing more serious complications from developing in the future.
Before administering any form of curative treatment, we first perform a physical examination and diagnostic testing to verify the presence of a coccidioides fungal infection. This includes listening to the animal’s lungs, taking x-rays, and typically running blood tests, as well.
Once a definitive valley fever diagnosis is reached, we can administer treatment primarily in the form of antifungal medications. We might also recommend additional treatments to ease symptoms and aid recovery.
