Is black mold causing our persistent cough and illness?« Back to Previous Page

Yes, the black mold you found is very likely the cause of your family's persistent cough and scratchy throat. In Dubai's humid climate, this type of growth is frequently caused by hidden moisture, like the AC leak you suspect. The constant air conditioning recirculates mold spores throughout your home, which can cause significant respiratory irritation, especially in children.

For a patch of that size and given the health symptoms, professional remediation is strongly advised. Do not attempt to clean it yourself, as disturbing it will release a massive amount of spores and can make the contamination much worse. The safest first step is to isolate the area—close the door to the room and avoid using that AC unit until it's inspected.

A proper remediation process involves identifying and fixing the moisture source first, then containing the area with physical barriers and negative air pressure to prevent cross-contamination. The moldy materials (like sections of the rug and potentially drywall or flooring underneath) must be carefully removed and disposed of. The area is then HEPA-vacuumed and cleaned with antimicrobial agents. Finally, post-remediation testing by an independent microbiology lab is the only way to verify the spore count has returned to safe, background levels.

Given your villa's location, ensure any company you hire follows the Dubai Municipality guidelines for environmental health and safety. Look for providers with certified mold remediators on staff who can provide a detailed scope of work and, crucially, will conduct third-party verification testing to prove the job was done correctly. Your health symptoms should resolve once the source is properly removed.
