Environmental control for fungal allergen exposure

Abstract

With our limited knowledge of the mold allergens, we must rely on common sense to reduce environmental exposure for patients who are allergic to mold. We understand that the first step is moisture control. Appropriate building design, keeping rainwater and ground water away from the interior, accomplishes this. In addition, the heating ventilation and air conditioning system must be appropriately designed and maintained. Functional maintenance of inside water sources such as free water from plumbing, appliances, and showers can prevent damaging leaks. Indoor humidity or water vapor must be controlled and maintained to prevent condensation on walls or in microenvironments, such as attics, bedrooms, basements, and beneath wall-to-wall carpeting. Few abatement trials have been published, but several suggest that such measures can reduce mold exposure. Copyright © 2003 by Current Science Inc.
