Is mold causing my kids' persistent cough?« Back to Previous Page

Based on your description, it is highly probable that the mold growth you discovered is the primary cause of your children's persistent cough. The damp smell from the AC vents is a classic indicator of microbial growth within the system, which then aerosolizes spores and distributes them throughout the bedroom. The patch under the carpet is a secondary colonization site, likely caused by condensation from the window or a minor leak, exacerbated by Dubai's high ambient humidity.

The black and green patch suggests a potential mixture of mold types, including Cladosporium (common on damp windows) and potentially Aspergillus. Inhalation of these spores and their mycotoxins is a well-documented irritant to the respiratory tract, particularly in children, leading to chronic coughing, wheezing, and allergic reactions.

For immediate action, I strongly advise against attempting a DIY remediation. Disturbing the mold without proper containment and air filtration will cause a massive release of spores, worsening the air quality and your children's symptoms. Do not use bleach, as it is ineffective on porous surfaces and can exacerbate respiratory issues.

The fastest and safest way to resolve this is to engage a professional mold inspection and remediation company like Saniservice. Our certified inspectors will conduct a comprehensive assessment, including air quality sampling to identify the spore types and concentration levels, and use borescopes to inspect the internal ducts of your AC system—a critical step often missed. Remediation involves isolating the area with negative air pressure, HEPA vacuuming, antimicrobial treatment of the AC system and affected building materials, and addressing the underlying moisture source (e.g., improving window sealing, checking for AC drain pan overflow).
