Valley fever on the rise in California, health officials warn

Cases of Valley fever,  a disease caused by a fungus common in some regions of California, are on the rise, state health officials announced this month. Over 5,500 provisional cases were reported in the first six months of the year.

In 2000, the state reported fewer than 1,000 cases; by 2019, the number had increased to over 9,000. The latest increase in cases comes after the Golden State reported 12,500 cases last year, the highest ever recorded in the state.

Valley fever, also known as coccidioidomycosis or “cocci,” is caused by a fungus that grows in the soil and dirt in some areas of California. Most common in the Central Valley and Central Coast, symptoms of the disease are similar to those of COVID-19 or the flu.

Health officials warn that Valley fever can lead to severe lung infections, including pneumonia.

Cases of the disease are the highest in the southern San Joaquin Valley, but cases have also been increasing in other parts of the state. Those who travel, attend school, or live in the area are at the highest risk.

Here’s how people can protect themselves and their furry friends from getting the disease:

• When it is windy outside and the air is dusty, stay indoors and keep windows and doors closed.
• When driving through a dusty area, keep car windows closed and use recirculating air, if possible.
• Before digging, wet down the soil and dirt to prevent dust from being stirred up into the air.
• Consider wearing a properly fitted N95 respirator (mask) if you must be in dusty air outdoors in these areas.

Valley fever can only be diagnosed by a doctor or healthcare provider, typically through blood tests or other laboratory tests. Anyone can get the disease, but adults 60 years old or older, those who have diabetes or a condition that weakens the immune system, or those who are pregnant, are at higher risk of developing Valley fever.

Black and Filipino people also have a higher risk of developing Valley fever, according to health officials.

Residents are encouraged to talk with their doctor if they are concerned about contracting Valley fever. More information about the disease can be found here.
