Exposures to biological agents indoors are a significant health hazard causing a wide range of health effects.
Dampness is a strong and consistent indicator of risk for asthma and respiratory symptoms, such as coughs and wheezing, related to indoor air quality. Inadequate ventilation and structural failures are often to blame. Proper ventilation controls humidity and prevention of condensation, and is also an important determinant of good indoor air quality.
This is a difficult area for public health policy-makers due to the great variety of indoor spaces, fragmentation of responsibilities and the limited mandate of public authorities for interventions.
WHO reviewed the available evidence on policy and interventions to protect health from the effects of home damp and mould. This review encompassed evidence and policy implications of actions implemented in various countries.
WHO Recommendations are being prepared on how policies and regulations can be applied to support and improve actions on damp and mould in indoor settings at local and national level. Key messages on suggested action by residents are provided in a brochure developed for the public by WHO and the Health and Environment Alliance (HEAL), a project partner. A list of institutions and agencies acting as advisory bodies on damp and mould problems to the public in European countries was compiled and made available online by HEAL.
