Could hidden mold cause our persistent cough and illness?« Back to Previous Page

Yes, the hidden mold you found is very likely the cause of the persistent coughs, headaches, and sore throats. In Dubai's climate, where high humidity and constant AC use create ideal conditions for mold, this is a common scenario. The mold growth behind your sofa, fueled by the AC condensate leak, is releasing spores and microbial volatile organic compounds (mVOCs) into the air you breathe, especially while sleeping.

The continuous exposure to these airborne particles is a known irritant to the respiratory system, causing the exact symptoms you describe. For children, whose immune systems are still developing, the reaction can be more pronounced and persistent.

Your immediate priority should be to stop the exposure. Move the sofa and avoid using that room until it's addressed. Do not attempt to clean it yourself with bleach or other household products, as this can aerosolize more spores and agitate the mold, potentially worsening the situation. The source of the moisture, the AC leak, must be repaired by an HVAC technician first to prevent immediate regrowth.

For a case of this size and with health symptoms already present, a professional inspection and remediation is strongly advised. They will contain the area, safely remove the contaminated materials, and use HEPA filtration to clean the air. Following remediation, a post-test by an independent microbiology lab is the only way to verify the air quality is safe and the allergen load has been measurably reduced for your family's return.
