Mold

How does mold affect asthma?

Molds can trigger asthma episodes in sensitive individuals with asthma.  People with asthma should avoid contact with exposure to molds.

Molds are microscopic fungi that live on plant and animal matter.  Molds can be found almost anywhere, and grow best in damp places such as kitchens, bathrooms, and basements.
