In 2000-2001 asthma prevalence was monitored at 6.5%; by 2010-2011 a 4.3% increase was shown, with asthma prevalence totaling 10.8% of Canada's population. [ 29 ] Furthermore, asthma prevalence varies among the provinces of Canada; the highest prevalence is Ontario at 12.1%, and the lowest is Nunavut at 3.8%. [ 29 ]
Asthma phenotyping and endotyping has emerged as a novel approach to asthma classification inspired by precision medicine which separates the clinical presentations of asthma, or asthma phenotypes, from their underlying causes, or asthma endotypes. The best-supported endotypic distinction is the type 2-high/type 2-low distinction.
The mechanisms behind allergic asthma—i.e., asthma resulting from an immune response to inhaled allergens—are the best understood of the causal factors. In both people with asthma and people who are free of the disease, inhaled allergens that find their way to the inner airways are ingested by a type of cell known as antigen-presenting ...

Plastic bronchitis (PB) is a disorder in which branching casts of the airways -- i.e., accumulations of fluid or tissue that are molded in the shape of the airway -- are expectorated.
Sensitizer-induced occupational asthma is an immunologic form of asthma which occurs due to inhalation of specific substances (i.e., high-molecular-weight proteins from plants and animal origins, or low-molecular-weight agents that include chemicals, metals and wood dusts) and occurs after a latency period of several weeks to years.

The development of asthma in children is likely due to environmental factors interacting with a susceptible host over the course of a short period between pre- and postnatal development. [5] Hartert studies the predictive factors of asthma development and the causal role of respiratory viral infections. [ 5 ]
