Could black mold from our flood be causing my son's symptoms?« Back to Previous Page

Yes, the black mold discovered after your villa's flood is a very plausible cause of your son's persistent runny nose and rash. In Dubai's humid climate, indoor mold growth from water damage is a common trigger for such symptoms, especially in children who are more sensitive. The rash could be a direct skin irritation from contact with mold spores or an allergic reaction.

The safest approach is to first have the mold properly identified. Not all black-colored mold is the infamous "toxic black mold" (Stachybotrys), but many types can cause health issues. A professional inspection and lab analysis can confirm the species and the extent of the contamination hidden behind walls or under flooring, which is crucial for determining the right remediation strategy.

For a small, visible patch (less than 1 square meter), you can carefully clean it yourself by misting the area with a diluted white vinegar solution to suppress spores, then wiping it away. Always wear an N95 mask, gloves, and goggles. However, given the history of flooding, the problem is likely more extensive than what is visible. Disturbing it without proper containment can aerosolize spores throughout your home's AC system, potentially worsening your family's exposure.

For any significant water damage, professional remediation is strongly advised. Companies specializing in this will set up containment barriers, use HEPA filtration units to clean the air, and ensure the area is completely dried to Dubai's stringent standards to prevent regrowth. Addressing the source of moisture is the most critical step to ensure it doesn't return.
