An estimated 6%-10% of the general population and How To Stop Water And Mold In A Crawlspace 15%-50% of those who are genetically susceptible are sensitized to mold allergens. 

Fifty percent of the 937 children tested in a large multi-city asthma study sponsored by the National Institutes of Health showed sensitivity to mold, indicating the importance of mold as an asthma trigger among these children. How To Stop Water And Mold In A Crawlspace Molds are thought to play a role in asthma in several ways. 

Molds produce many potentially allergenic compounds, and molds may play a role in asthma via release of irritants.
