Household Molds Linked to Childhood Asthma

Three specific species of mold were more common in the homes of babies who later developed asthma. The finding highlights the importance of preventing water damage and mold growth in households with infants.

More than 6 million children in the U.S. have asthma. Genes are known to play a role, and so does the home environment. Childhood asthma has been linked to indoor mold growing in a child’s home as a result of moisture problems such as water leaks. The connection between mold and asthma, however, is complicated and not fully understood. Asthma is often associated with allergies, and molds spread by releasing tiny spores into the air, which can cause allergic reactions.
