What is Histoplasmosis?

An infection caused by breathing in spores of a fungus that can be found in bird and bat droppings is known as histoplasmosis. The infection is most commonly transmitted when these spores get airborne which usually happens during cleanup or demolition projects.

The infection can also be transmitted through soil that has been contaminated by bird or bat dropping. This puts the farmers and landscapers at a higher risk of the disease.

In most cases the symptoms of histoplasmosis do not develop and the patients are not aware that have been infected. However, in some patients especially in infants and those with a weak immune system histoplasmosis can take a serious shape.
