What is Valley Fever and How Can it be Prevented?

Valley Fever, also known as coccidioidomycosis, is caused by inhaling spores of the fungus Coccidioides.

These spores are found in the soil of areas with arid climates, such as the southwestern United States and parts of Central and South America. When the soil is disturbed, such as during construction or sandstorms, the spores become airborne, making it easy for people to inhale them.

Once inhaled, the Coccidioides spores can cause a range of symptoms, from mild flu-like symptoms to severe respiratory distress.

It’s important to note that not everyone who inhales the spores will develop symptoms. In fact, many people may never know they have been infected.

Prevention is key in mitigating the risk of Valley Fever. By taking some simple precautions, you can greatly reduce your chances of becoming infected. Here are some effective prevention methods:

Mitigating the Risk of Contracting Valley Fever

If you live, work, or operate in an area where the fungus Coccidioides is present, there are some steps you can take to reduce the risk of inhaling the spores:

Avoid Dusty Environments: Because the fungus is found in soil, it’s important to avoid activities that may disturb the soil and create dust, such as construction work, farming, or gardening during windy conditions.

Using Personal Protective Equipment (PPE): If you must be within the environment, wear a mask to reduce the risk of inhaling fungal spores.

Staying Indoors During Dust Storms: If you live in an area prone to dust storms, stay indoors with windows closed during windy conditions, especially if you have respiratory issues or are immunocompromised.

Keeping Indoor Environments Clean: Regularly clean and vacuum indoor spaces to reduce the accumulation of dust, which may contain fungal spores.

Moistening Soil: If you’re working with soil in your garden or yard, moisten it before disturbing it to help prevent the release of fungal spores into the air.

Using Air Filtration Systems: Consider digging with heavy equipment having enclosed, air-conditioned HEPA-filtered cabs, especially if you live in an area where valley fever is prevalent.

Awareness and Early Detection: Be aware of the symptoms of valley fever, which include fever, cough, chest pain, and fatigue, among others. If you develop symptoms after being in an area where the fungus is prevalent, seek medical attention promptly for diagnosis and treatment.

Educating Yourself: Learn more about valley fever and its risk factors, especially if you live in or plan to travel to endemic areas. Understanding how the fungus spreads can help you take appropriate precautions to avoid exposure.

While these measures can help mitigate the risk of valley fever, it’s essential to remember that the fungus is naturally occurring in certain regions, and complete avoidance may not be possible. However, taking proactive steps to minimize exposure can significantly reduce the likelihood of infection.

If you have specific concerns or live in an area where valley fever is prevalent, consulting with a healthcare professional or local public health authorities for personalized advice is recommended.


Preventing Valley Fever in Construction

Of course, there is a much bigger responsibility for those who manage or are responsible for construction projects in an area where Valley Fever is a risk.

Preventing valley fever among construction workers, and members of the general public,  involves implementing various measures to reduce exposure to the fungal spores that cause the disease. Here are some strategies:

Risk Assessment: Conduct a thorough assessment of construction sites to identify areas with a higher risk of exposure to fungal spores, such as dusty soil or excavation sites.

Educate Workers: Provide training and educational materials to construction workers about the risks of valley fever, including how it is transmitted and its symptoms. Workers should understand the importance of taking preventive measures.

Use Personal Protective Equipment (PPE): Require workers to wear appropriate PPE, such as N95 respirators or masks, when working in dusty environments where soil may be disturbed. Ensure that workers receive proper training on how to use and maintain their respiratory protection equipment.

Minimize Dust: Implement dust control measures at construction sites to minimize the generation and spread of dust. This may include watering down work areas, using dust suppressants, and employing equipment with dust control features.

Schedule Work Wisely: Plan construction activities to minimize exposure to dusty conditions, such as avoiding outdoor work during windy or dusty weather conditions when fungal spores are more likely to become airborne.

Provide Rest Areas: Designate clean, dust-free rest areas where workers can take breaks and seek refuge from dusty conditions. Encourage workers to use these areas to reduce their overall exposure to airborne dust.

Maintain Good Hygiene Practices: Encourage workers to practice good hygiene, such as washing their hands and face frequently, especially before eating or drinking. Provide access to handwashing facilities and hand sanitizers on-site.

Monitor Worker Health: Encourage workers to report any symptoms suggestive of valley fever, such as persistent cough, fever, or fatigue, to their supervisors or occupational health personnel promptly. Establish protocols for monitoring and responding to suspected cases of valley fever among workers.

By implementing these preventive measures and promoting a culture of safety awareness, construction companies can help reduce the risk of valley fever among their workers and create a healthier and safer work environment.
