Could hidden mold be causing our constant coughs?« Back to Previous Page

Yes, hidden mold is a very likely cause of the persistent coughs, headaches, and sore throats you're describing. The proximity to your sleeping area is particularly concerning, as you're exposed for long periods. In Dubai's humid climate, especially in older Deira buildings, condensation from AC units is a common source of moisture that leads to mold growth behind furniture and inside walls.

The type of mold matters. While not all black molds are the notorious Stachybotrys, many species commonly found in damp indoor environments produce irritants and allergens. Inhaling these spores and microbial volatile organic compounds (mVOCs) directly causes the respiratory symptoms you've listed, particularly in children who are more sensitive.

Your first step is to stop the moisture source. Have an AC technician inspect and repair the suspected leak immediately. Do not attempt to clean the large patch yourself, as improper disturbance will aerosolize a massive amount of spores throughout your apartment. For a hidden infestation of this size, a professional inspection is strongly advised to assess the full extent behind the walls.

They should use a borescope to look inside the cavity and recommend a remediation plan. Reputable companies will show you before-and-after lab results to verify the spore count has been returned to safe, outdoor levels. Until it's handled, keep the area isolated and increase ventilation if possible.
