Valley Fever cases in California continue to increase

Valley Fever cases in California

A potentially deadly illness found in the soil and dusty winds of California's Central Valley is on the rise, state health officials say.

Documented cases of Valley Fever rose 11 percent in 2018 — a preliminary total of 7,886 cases compared to 7,090 cases for the same period in 2017, according to the California Department of Public Health. Health officials said final data for 2018 will be available in March.

Valley Fever (coccidioidomycosis) is an illness caused by a fungus found in the soil and dirt in the Central Valley.

The Rise of Valley Fever

Two years ago California saw more than 6000 cases of a serious and sometimes fatal airborne infection called Valley Fever. In 2017 that number jumped to more than 8000 cases. That figure will likely rise again this year in California, as well as Arizona, Nevada, New Mexico, Texas and Utah where the fungus that causes Valley Fever is found. If you live in one of those states, you may have had the infection, but didn’t know it. The symptoms are easily confused with pneumonia and it’s commonly misdiagnosed.
