MOLD & HEALTH
Modest wetting and drying in buildings and in ventilation systems is normal and generally poses little risk for occupant health. Similarly, very brief episodes of wetting are not usually a problem provided that steps are taken to rapidly dry all materials. “Dampness” is the presence of unwanted and excessive moisture in buildings. This can lead to the growth of mold, fungi, environmental bacteria, and, in homes, house dust mites.
Well conducted epidemiology studies in several countries have consistently shown that exposures from building/house dampness and mold have been associated with increased risks for respiratory symptoms, asthma, hypersensitivity pneumonitis, rhinosinusitis, bronchitis, and respiratory infections. In studies conducted in the nonindustrial workplace, individuals with asthma or hypersensitivity pneumonitis were found to be at risk for progression to more severe disease if the relationship between illness and exposure to the damp building was not recognized and exposures continued.
