Black mold in bedroom: heath risk and removal in Dubai?« Back to Previous Page

That black patch is likely causing the symptoms. The high humidity in Dubai and year-round AC use create ideal conditions for mold, especially in closets backing onto bathrooms where condensation forms. The persistent cough and runny nose in a child are common reactions to mold spores.

Vinegar only removes surface discoloration; it does not address the moisture source or the hyphae (roots) growing into the porous wall material, which is why the musty smell returns. For a permanent fix, the moisture intrusion must be identified and stopped first. This could be condensation from the AC, a small plumbing leak from the adjacent bathroom, or inadequate ventilation.

The most effective method is to have a professional inspection to identify the exact moisture source and the extent of the contamination. For a small patch, they may remove the affected section of drywall, treat the cavity with an antimicrobial solution, and seal it before repainting. DIY attempts often just disturb the spores, spreading them further.

For your son, a visit to a pediatrician or an allergist is recommended. Inform the doctor about the mold discovery, as this is a key diagnostic clue. They can assess for allergies or other respiratory reactions. In many cases, symptoms clear up once the mold source is properly remediated and the air quality improves.
