The California Department of Public Health (CDPH) is warning residents and visitors about the ongoing risk of Valley fever, also known as coccidioidomycosis or “cocci,” which is caused by a fungus that grows in the soil and dirt. The risk remains high in 2025, particularly in areas such as the Santa Clarita Valley, Central Valley, and Central Coast.
Valley fever can occur at any time of the year but is more common during late summer and fall when people breathe in the fungus, leading to symptoms like cough, fever, trouble breathing, chest pain, and tiredness. CDPH recommends that individuals experiencing these symptoms seek medical attention immediately.
The fungus grows in areas where it rains after droughts and can be stirred up by dry, windy weather, construction, or outdoor activities. People and pets can get Valley fever by inhaling dust containing the fungus. The disease is not contagious but can be severe, chronic, or fatal if left untreated.
High case counts have been reported this year, with over 5,500 provisional cases in the first six months of 2025. This marks a significant increase from previous years, especially in areas like the southern San Joaquin Valley and Central Coast regions.
To reduce the risk of getting Valley fever, individuals can take precautions such as staying indoors when windy and dusty, wearing N95 respirator masks outdoors, and being aware of symptoms. Only a doctor or healthcare provider can diagnose Valley fever through blood tests or other laboratory tests.
The CDPH is urging residents to be aware of their risk factors, including age, diabetes, weakened immune systems, pregnancy, and underlying health conditions. By knowing the signs and symptoms and seeking medical attention promptly, individuals can reduce the severity of the disease.
