The
prevalence of allergic
diseases is rising in
children as a result of complex
gene-environment interactions.
Environmental exposures can dramatically influence the
phenotype of allergic
diseases,including
atopic eczema,
asthma,and
allergic rhinitis.Environmental factors associated with allergic
diseases include
chemical pollutants and
allergens in the
air,as well as other
environmental exposures such as the
microbiome.Indoor and outdoor
air pollutants and
allergens play an important
role in the inflammatory response and clinical manifestations of
allergic reactions caused by
allergens.Strengthening environmental control and controlling
environmental exposure is an important way to prevent allergic
diseases.
