It is recognized more often in immunocompromised individuals, such as AIDS patients. The disease is acquired by inhaling the spore stage of the fungus. Outbreaks may occur in groups with common exposures to bird or bat droppings or recently disturbed, contaminated soil found in chicken coops, caves, etc.
Symptoms vary from mild to severe, ranging from flu-like illness to serious lung infection.

Specific medications such as Amphotericin B are available. Minimize exposure to dust in contaminated and enclosed environments such as chicken coops and their surrounding soil. Use of a protective mask and spraying the area with water may be helpful in minimizing exposure to dust.
