Valley fever cases in San Luis Obispo surged in 2024, with 482 cases—double the 244 reported the previous year, officials say. This exceeds the previous peak of 445 instances in 2017 and is the most cases since records began.
Explain Valley Fever.
Valley fever cases in San Luis Obispo stem from Coccidioides spores in local soil, common in California’s Central Valley region. The infection is developed by inhaling airborne fungus spores, which are often disturbed by wind, digging, or driving through dusty areas.
Warning Signs and Risks
- Approximately 60% of infected people show no symptoms at all.
- Flu-like symptoms, such as cough, fever, exhaustion, and shortness of breath, affect between 30 and 40 percent of people.
- In rare cases (around 1%), the infection spreads to other parts of the body and becomes serious.
- If symptoms persist for more than a few weeks, health officials urge residents to ask for a Valley fever test.
Why the Surge in Cases?
Health Officer Dr. Penny Borenstein attributes the increase to environmental factors, saying:
“Valley fever is known to increase after periods of drought followed by heavy rain.”
The recent weather patterns have likely promoted fungal growth in soil, raising the risk of exposure.
Ways to Lower Your Risk
Although dust control is essential for prevention, valley fever cannot be transmitted from person to person:
- Steer clear of dusty locations, especially when the wind is strong.
- When working outside or near soil, put on a N95 mask.
- Before gardening or excavating, moisten the soil.
- In dusty places, keep the automobile windows closed and turn the air conditioner on recirculation.
- Take the same care as you would with animals because dust can also infect pets with Valley fever.
