could black mold in my closet cause kids' persistent cough??« Back to Previous Page

Yes, the black mold behind your storage box is very likely the cause of your children's persistent cough. Mold releases microscopic spores and microbial volatile organic compounds (mVOCs) that are respiratory irritants, and children are particularly susceptible. The constant, low-level exposure from a hidden source like this often manifests as a chronic cough, congestion, and worsened allergy symptoms, especially in Dubai's climate where AC recirculates indoor air.

For a situation of this scale and duration, professional remediation is the safest approach. Disturbing it yourself risks aerosolizing a massive number of spores, contaminating your entire home's air system. In Dubai, look for a company that follows IICRC S520 standards for mold remediation. The process should involve:
1. Sealing off the affected area with plastic sheeting to contain spores.
2. Using HEPA-filtered negative air machines to create negative pressure, preventing spore escape.
3. Carefully removing the moldy materials (e.g., drywall, insulation).
4. HEPA vacuuming and wiping down all surfaces.
5. Drying the area completely to prevent regrowth.

Crucially, the job isn't complete without verification. Request a post-remediation verification (PRV) test from an independent third party, not the remediation company itself, to confirm spore counts have returned to normal indoor levels. Saniservice's microbiology lab, for instance, provides this specific evidence-based testing. Given the high humidity and constant AC use, also ask them to identify the moisture source—likely condensation from an AC line in the wall or a small leak—to prevent it from returning.
