Could closet mold be causing my kids' persistent coughs?« Back to Previous Page

My kids have been coughing non-stop since we got back from the summer break, and I’ve just spotted patches of black, fuzzy mold in the closet of our master bedroom where all our winter clothes were stored. It’s on the back wall, and the room always felt damp. Could this mold in the closet be the reason for their persistent coughs, and what’s the safest way to clean it without making the spores spread through the AC?

Yes, the black mold in your closet is very likely contributing to your kids' persistent coughs. The damp, enclosed space is a perfect breeding ground, and the airborne spores they're breathing can cause significant respiratory irritation, including chronic coughing, congestion, and worsened allergy symptoms. This is especially common in Dubai's climate, where high humidity and year-round AC use can lead to condensation and trapped moisture in poorly ventilated areas like closets on external walls.

The safest approach is to avoid disturbing it yourself. Cleaning visible patches without proper containment can aerosolize spores, spreading them through the air and into your AC system, which then circulates them throughout the home. For a small area (under one square meter), you can carefully wipe it with a damp cloth and a detergent solution, but you must wear an N95 mask, seal off the room, and ensure the AC is turned off first. However, given the location on the wall and the pre-existing dampness, the visible growth is likely just the surface manifestation of a deeper moisture issue.

For a situation like this, a professional inspection is strongly advised. They can identify the source of the dampness—often condensation from a cold wall or a hidden leak—and assess the full extent of the growth. Remediation involves containing the area with negative air pressure, HEPA-filtered air scrubbers to capture spores, and safe removal techniques. Afterwards, a post-remediation verification test, ideally from an independent microbiology lab, is the only way to confirm the allergen load in the air has been successfully reduced to a safe level. Addressing the root cause, such as improving ventilation or adding insulation to the cold wall, is crucial to prevent it from returning.
