California has reported 6,761 cases of Valley Fever by the end of July 2025, potentially breaking last year’s record of 12,595 cases. The fungus that causes the illness, which is spread through airborne spores, poses significant risks due to climate change.
Valley Fever, also known as coccidioidomycosis, primarily affects humans and animals living in southwestern states, including California. Symptoms include fever, coughing, chest pain, and fatigue, often leading to misdiagnosis or delayed treatment.
High-risk groups include pregnant women, those with weakened immune systems, people over 60, individuals with diabetes, and workers exposed to dust and dirt. In severe cases, the infection can spread beyond the lungs, affecting other parts of the body.
According to the Centers for Disease Control and Prevention (CDC), some patients may experience severe or permanent lung difficulties, while others may require treatment, hospitalization, and antifungal medication. The CDC warns that climate change is contributing to the increasing number of Valley Fever cases in the US since 2000, with a notable spike in 2019.
Researchers and health officials are alarmed by the rising trend, urging caution and proper diagnosis for those suspected of having Valley Fever.
