Allergy to mold, dander, dust

Prevention:

There is no known way to prevent allergies. Symptoms may sometimes be prevented by avoiding known allergens.

Mold spores are everywhere. Minimize exposure by keeping rooms dry (using a dehumidifier if necessary). Stay indoors during summer and fall, when mold is most prevalent. Discard moldy or mildewed articles (books, toys, shoes, and so on). Use synthetic fabrics for clothing and household furnishings whenever possible. Disinfect bathrooms, basement walls, and furniture with diluted bleach or other appropriate disinfectant solution.

Dust exposure is minimized by frequent cleaning. Vacuum frequently, preferably using a
small-pore filter to capture dust mites. Damp-mop and dust often. Eliminate as many "dust catchers" as possible, including rugs, bed ruffles or canopies, and curtains. Wash rugs, bedding, and furniture coverings weekly if possible. Central heating and air-conditioning systems may be helpful, particularly if they include special filters to capture dust.

People who are allergic to animals may need to avoid keeping pets. Frequent bathing and
grooming of the pet (preferably by someone who is not allergic to the animal) may allow some people to keep their pet. Allergy to animals may also include allergic reaction to wool, which may contain tiny amounts of dander (skin scales).

Avoid other environmental irritants whenever possible.
