Could this mold cause my kids' cough and congestion?« Back to Previous Page

Yes, the mold you found is very likely causing or significantly worsening your kids' cough and congestion. The black mold growing on a damp wall is a classic scenario in Dubai, where high humidity and air conditioning use create ideal conditions for growth. The continuous exposure to mold spores in their bedroom, especially overnight, directly irritates the respiratory tract, leading to persistent symptoms like coughing, stuffy noses, and worsened allergies.

The dampness suggests a moisture issue, which must be addressed first. This could be from a small pipe leak within the wall, condensation from an AC unit, or moisture wicking from the concrete slab—a common issue in older Dubai villas. Simply cleaning the visible mold is not enough; the source of the water must be identified and fixed to prevent it from returning immediately.

For a case like this, a professional inspection is strongly recommended. They can use moisture meters and borescopes to find the hidden source of the dampness without unnecessary damage. The visible mold should be remediated by experts who will contain the area to prevent spores from spreading throughout your home during cleaning. After remediation, an independent clearance test, typically an air quality test, is the only way to verify the spore count in the room has returned to a safe level.

Until you can get it professionally assessed, improve ventilation in the room as much as possible and keep the children out of that space. Do not attempt to clean it yourself with bleach, as this can agitate the spores and potentially make the airborne contamination worse.
