Could hidden mold be causing our persistent cough?« Back to Previous Page

Yes, the hidden mold you found is very likely causing your family's persistent cough and scratchy throat. This is a common scenario in Dubai villas, where high humidity and condensation from AC systems create ideal conditions for mold growth behind furniture or in poorly ventilated corners.

The type of black mold commonly found in these damp situations (often Cladosporium or Aspergillus) produces allergens and irritants. Inhaling these spores directly causes respiratory symptoms like coughing, congestion, and throat irritation, particularly in children who are more sensitive. Your description of symptoms improving when away from home and worsening upon return strongly points to an indoor environmental cause.

For a case of this size and with health symptoms already present, professional assessment is strongly recommended. DIY cleaning is not advised as it can disturb a large colony and cause a significant release of spores throughout your home. A proper inspection will identify the moisture source (like that slow leak) and the full extent of the growth, which often spreads behind walls.

Look for a provider that uses a moisture meter to find hidden dampness and can conduct air or surface sampling to identify the mold species. This is crucial, as it confirms the problem and provides a baseline for verifying that remediation was successful. In Dubai's climate, simply cleaning the visible mold without fixing the underlying moisture problem will result in it returning quickly. The goal is to make the area dry and inhospitable to mold permanently.
