Valley fever cases are rising across California once again, with the state expected to reach record levels this year. According to the California Department of Public Health (CDPH), over 5,500 provisional valley fever cases have been reported as of July 31, surpassing last year’s count of 12,500 cases.
Historically, the disease is most common in the Central Valley and Central Coast areas, but recent cases are also emerging in the Bay Area. Alameda County has reported 72 cases, while Contra Costa County has seen 105 cases. The increase in valley fever cases outside these traditional hotspots suggests that the disease is no longer confined to specific regions.
Climate change experts attribute the rise in valley fever cases to changing weather patterns, which create an ideal environment for the fungus that causes the disease to thrive. Whiplashed cycles of wet weather followed by drought are believed to be contributing factors.
Residents in areas where valley fever is common should take precautions to minimize their risk of exposure. While the disease is not contagious, it can still cause severe illness in some people. The CDPH recommends avoiding outdoor activities during dust storms and wearing N95 masks in high-risk areas like construction sites.
Symptoms of valley fever include fatigue, cough, fever, headache, shortness of breath, night sweats, muscle aches, and joint pain. If symptoms persist for more than a week, it is essential to seek medical attention. The disease can be diagnosed with a blood test or skin test, and treatment typically involves a three- to six-month course of oral antifungal medication.
Certain groups are at higher risk of developing severe disease from valley fever, including older adults, pregnant people, people with diabetes, and those with weakened immune systems. To reduce their risk, residents can take steps such as keeping car windows closed during dusty weather and using air filtration indoors.
While there is currently no vaccine available, scientists are working on a new vaccine to prevent valley fever. In the meantime, taking preventative measures can help minimize the risk of exposure.
