Dust Storms, Valley Fever, and Public Awareness.

Area of Science:

• Environmental Science
• Public Health
• Mycology

Background:

• Valley fever (coccidioidomycosis) is a fungal disease endemic to arid regions.
• Dust storms are recognized as a potential transmission vector for the causative fungus, *Coccidioides*.
• Previous studies have utilized crowdsourced data to investigate the relationship between dust storms and Valley fever incidence.

Purpose of the Study:

• To critically evaluate the methodology and data used in a crowdsourced study on dust storms and Valley fever.
• To identify inconsistencies in the definition and data collection of "dust storms" in scientific literature and databases.
• To emphasize the public health implications of accurately assessing population exposure to dust-borne pathogens.

Main Methods:

• Review and critique of existing dust storm data, including the National Oceanic and Atmospheric Administration (NOAA) Storm Events Database.
• Analysis of the limitations of crowdsourced datasets for epidemiological studies.
• Discussion of factors influencing pathogen transport, such as dust event frequency, magnitude, and duration.

Main Results:

• Inconsistencies exist in the scientific community's definition and reporting of "dust storms."
• NOAA dust data is heterogeneous and unsuitable for precise correlation with Valley fever outbreaks.
• Accurate assessment of population exposure requires detailed data on dust event characteristics.

Conclusions:

• Current dust storm data is insufficient for robustly linking dust events to Valley fever transmission.
• Improved data collection and standardized definitions are crucial for understanding and mitigating Valley fever risk.
• Public health messaging should reflect the potential risk of Valley fever transmission via dust storms.
