Valley fever or coccidioidomycosis is a fungal infection resulting from the coccidioides organism. Most infections occur after inhaling fungal spores, but the spores may also enter through the eyes or an open wound. Symptoms can vary significantly between cases, and infections also progress through several forms, causing a wide range of health issues.


1. Flu-Like Symptoms

Acute valley fever often presents with flu-like symptoms that range from minor to severe. Some of the most common symptoms are fever, tiredness, headache, and chills. Because the infection usually begins after inhaling spores, respiratory issues like shortness of breath and coughing are also typical. The course of valley fever is extremely variable and symptoms may improve or worsen depending on many factors.
