text: The most common form of hypersensitivity is caused by the direct exposure to inhaled mold spores that can be dead or alive or hyphal fragments which can lead to allergic asthma or allergic rhinitis.  The most common effects are rhinorrhea (runny nose), watery eyes, coughing and asthma attacks.  Another form of hypersensitivity is hypersensitivity pneumonitis.  Exposure can occur at home, at work or in other settings.   It is predicted that about 5% of people have some airway symptoms due to allergic reactions to molds in their lifetimes.
  Hypersensitivity may also be a reaction toward an established fungal infection in allergic bronchopulmonary aspergillosis.
