<unk>  is a fungal infection of usually the lungs, caused by the genus Aspergillus, a common mold that is breathed in frequently from the air around, but does not usually affect most people. It generally occurs in people with lung diseases such as asthma, cystic fibrosis or tuberculosis, or those who have had a stem cell or organ transplant, and those who cannot fight infection because of medications they take such as steroids and some cancer treatments. Rarely, it can affect skin.<unk>  occurs in humans, birds and other animals.<unk>  occurs in chronic or acute forms which are clinically very distinct. Most cases of acute<unk>  occur in people with severely compromised immune systems, e.g. those undergoing bone marrow transplantation. Chronic colonization or infection can cause complications in people with underlying respiratory illnesses, such as asthma, cystic fibrosis, sarcoidosis, tuberculosis, or chronic obstructive pulmonary disease. Most commonly,<unk>  occurs in the form of chronic pulmonary<unk>  (CPA), aspergilloma, or allergic bronchopulmonary<unk>  (ABPA). Some forms are intertwined; for example ABPA and simple aspergilloma can progress to CPA. Other, noninvasive manifestations include fungal sinusitis (both allergic in nature and with established fungal balls), otomycosis (ear infection), keratitis (eye infection), and onychomycosis (nail infection). In most instances, these are less severe, and curable with effective antifungal treatment. The most frequently identified pathogens are Aspergillus fumigatus and Aspergillus flavus, ubiquitous organisms capable of living under extensive environmental stress. Most people are thought to inhale thousands of Aspergillus spores daily but without effect due to an efficient immune response. Taken together, the major chronic, invasive, and allergic forms of<unk>  account for around 600,000 deaths annually worldwide.
