Thus, recognition of environmental triggers is
fundamental in attempts to prevent allergic asthma.
Fungal spores are also an important problem for
asthmatic patients in buildings with damp (Becker,
2008). The role of fungal allergens as the primary
extrinsic factor and a dominant factor in asthma
severity has been incompletely explored. Fungi can be linked to the severity of asthma such as
through inhalation of fungal spores, fungal
sensitization or causation of allergic
bronchopulmonary mycosis and respiratory
system damage (Bateman et al., 2008; O'Driscoll,
2005). Some studies have shown that exposure to
environmental fungi increased the risk of death
from asthma. However, fungal sensitization seems
to be more prevalent in populations of patients with
severe asthma. In older adults, asthma mortality
and hospital admissions are more common during
the winter, and in younger adult population in
periods of high ambient allergen load: [the cause
of] asthma in younger adults is usually allergic and
in older adults is usually non-allergic' (Denning,
2006).
