摘要: Of the chronic diseases affecting grade-school children, asthma is most common and accounts for greatest number of school days missed. Moreover, it can influence family dynamics function in other ways, unfortunately, also be associated with mortality, particularly inner-city environments United States. Thus understanding factors that lead to its development early life essential developing strategies aimed at primary prevention.

Both these appear exert their influences within first few years life, such becomes established before child enters grade age 5 6 years. Therefore, because both viral bacterial occur children who do not asthma, paramount identify genetic environmental activate, interact with, and/or direct immune system components along pathways allow become expressed clinically.
