  • Valley Fever Is an Occupational Illness Lets Get the Data to Prevent It
    Valley Fever Is an Occupational Illness: Let's Get the Data to Prevent It
    Bartels, Juliana G. E. ;
    Head, Jennifer R.
    2025/11/01 | Am J Ind Med 2025 Nov; 68(11):929-932 | National Institute for Occupational Safety and Health (NIOSH)
    Valley fever is a fungal disease acquired through inhalation of spores of the fungus Coccidioides. Spores become airborne when soil is disturbed, making outdoor workers, such as agricultural or construction workers, at higher risk of exposure and disease. Valley fever is endemic and increasing in the American Southwest, with numerous documented out ...
