I do not know if there is a diverse cause of aspergillus in my case it was the mold with the same name. Apparently some people develop a terrible allergy to it, which creates lung inflammation capable of scaring the lungs which at some point creating a situation where you would either need a transplant of lungs or you would continue to fail.
I do know that hypersensitive pneumonitis can be contracted from being a baker(flour dust) or worm beds or farmer or any other life activity that causes constant irritation to lungs. Oftentimes people who keep birds can catch this condition from the bird droppings. Apparently even a hot tub that is mismanaged with its chemicals can give someone hypersensitive pneumonitis aspergillus.
