Aspergillosis is disease cause by a mold named aspergillus. It was identified by an Italian priest and biologist in 1729 named Pier Antonio Micheli. There are many different kinds of aspergillosis. There are nearly 200 molds found in nature all around the globe of the same genus.
One variation causes allergic bronchopulmonary aspergillosis, a condition where the fungus causes allergic respiratory symptoms, such as wheezing and coughing, but does not actually invade and destroy tissue. The variation addressed in this report is invasive aspergillosis attributed to aspergillus fumigatus. This disease typically affects people with immune system problems. A weak immune system allows the fungal growth to invade the body and damage tissues. It primarily affects the lungs. It can infect many other organs as well and spread throughout the body.

Is Aspergillosis Contagious?
Aspergillus fumigatus is an opportunistic fungi. It rarely, if ever, effects an otherwise healthy person. Invasive aspergillosis most often affects people with weak or suppressed immune systems. Those with diabetes, COPD (chronic obstruction pulmonary disease), transplant patients, and people receiving chemotherapy for cancers such as leukemia are most at risk. Persons with advanced HIV infection can acquire the infection but is somewhat unlikely.

Fungus is so common in our environment that we breathe in aspergillus spores every day without even knowing it. In fact, it is so common that it would be impossible not to breathe it into your lungs at some point. People with healthy immune systems need not be concerned as the immune system removes the spore and renders them harmless. However, if you have a compromised immune system, breathing in aspergillus spores can easily lead to infection. Very dusty places such as building renovations or construction have been linked to allergic bronchopulmonary aspergillosis. Contaminated biomedical devices have even been determined to be the cause of Aspergillus skin infections.
