What lung disease is commonly associated with bat guano?

Histoplasmosis is the lung disease most commonly associated with bat guano. This fungal infection is caused by inhaling spores from the fungus Histoplasma capsulatum, which thrives in environments rich in organic material, such as bat droppings. When guano accumulates, it can create a perfect breeding ground for the fungus, which becomes airborne when disturbed.

Individuals exposed to the spores may develop respiratory symptoms, ranging from mild flu-like symptoms to severe lung disease, especially in those with weakened immune systems. This illustrates the importance of proper precautions when handling bat guano, particularly in areas where bats roost.

While asbestosis is caused by exposure to asbestos fibers, pneumonia refers to an infection of the lungs that can be caused by various pathogens, and COVID-19 is a viral respiratory illness caused by the coronavirus SARS-CoV-2, none of these conditions are directly linked to exposure to bat guano like histoplasmosis is.
