Histoplasmosis is a fungal infection caused by *Histoplasma capsulatum*. It primarily affects the lungs but can disseminate to other parts of the body, especially in individuals with weakened immune systems. This disease is most common in regions with soil contaminated by bird or bat droppings, notably the Ohio and Mississippi River valleys in the US.
Transmission methods vary. Please consult CDC or WHO resources for specific information.
