Valley Fever Awareness Week begins today. Taking steps to stay safe from Valley fever (also called coccidioidomycosis) is especially important in Arizona, where the fungus that causes the lung infection grows naturally in the soil.
Two-thirds of all Valley fever cases in the nation are reported in Arizona and the number of cases in the state has been noticeably increasing since 2016. In 2022, more than 9,500 Arizonans contracted Valley fever and 75 died from the disease.
The late fall and winter months, specifically from November to January, have historically had a higher number of cases. When wind, gardening, farming, yard work, or construction disturbs the soil the fungus lives in, the fungus can become airborne and enter people’s (and animals’) lungs, making them ill.
Some people are particularly vulnerable to severe illness from Valley fever. Older adults, people with weakened immune systems, people with diabetes and pregnant people should especially take measures to protect themselves.
A few ways you can protect yourself:
- Avoid blowing dust.
- Stay inside during a dust storm.
- Wet the ground when doing any gardening or construction work.
- Wear an N95 respirator if you expect to be exposed to blowing dust.
- Wash your hands thoroughly after working in the soil.
In addition to avoiding exposure to Valley fever, Arizonans should learn the signs and symptoms of Valley fever and be sure to ask their healthcare provider for a test if indicated.
Of note: Arizona Department of Health Services is hosting its annual 2023 Valley Fever Awareness Art Contest! All Arizona residents ages 6 and older are encouraged to participate. For more information, view the 2023 art contest entry form.
Dr. Eugene Livar is the assistant director for Public Health Preparedness at the Arizona Department of Health Services (ADHS). He has been part of the ADHS team since 2012.
