Is black mould causing my kids' cough?« Back to Previous Page

Black mould exposure is a common cause of persistent coughing, congestion, and respiratory irritation in children, especially in Dubai's humid climate where indoor spores can thrive. The continuous cough you describe, coupled with the visible growth near your AC unit, strongly suggests a connection. In many older Deira buildings, AC systems can act as a distribution network for these spores throughout the home.

For a confirmed diagnosis, a professional indoor environmental assessment is recommended. This is not just about removing the visible patch; it's about identifying the source of moisture and the extent of contamination within your AC system and building materials. DIY cleaning with bleach is often ineffective on porous surfaces and can aerosolize spores, potentially worsening the problem.

The safest approach is to first have the mould professionally inspected to assess the scope. Remediation for a case like this typically involves isolating the area, using HEPA filtration to capture airborne spores, removing and properly disposing of contaminated materials like drywall or insulation, and then treating the area with specialized antimicrobial agents. Crucially, the underlying moisture issue must be fixed to prevent immediate regrowth.

Given the age of the building and the AC's role, have the entire duct system evaluated for mould colonization and dust accumulation, which is very common with year-round usage. Once remediation is complete, maintaining indoor humidity below 60% with dehumidifiers or well-serviced AC units is essential to prevent its return. For health concerns, always consult a pediatrician and share these environmental findings.
