Indoor air quality, fungi, and health. How do we stand?
1Interuniversity Occupational and Environmental Health Clinic, Thoracic Institute, Montreal. nking@santepub-mtl.qc.ca
Objective:
To equip medical practitioners with up-to-date scientific and medical information on the health effects of exposure to fungi in indoor air, clinical evaluation of these health problems, and possible preventive measures.
Quality Of Evidence:
MEDLINE was searched from 1985 to 2000 using the MeSH words mould (mold), fungus, indoor air, and health effects. Nearly all studies were case reports, case-control studies, and cross-sectional studies. Evidence of an association between respiratory problems and the presence of fungi and dampness is strong.
Main Message:
Recent well designed studies and literature reviews indicate that exposure to dampness and fungi in indoor air brings on or exacerbates asthma and other respiratory complaints. More studies are required, however, before a definite conclusion on other potential effects of such exposure (such as systemic and long-term effects and pulmonary hemorrhage in infants) is possible. The various health problems that can result from exposure to dampness and fungi in indoor air make such exposure unacceptable from a public health perspective. Physicians are important in treating and preventing such problems; various resources are available to help them.
Conclusion:
Even though some scientific issues remain to be resolved concerning the health effects of exposure to dampness and fungi in indoor air, family physicians can identify potential problems and refer patients to appropriate resources.
Insights
Exposure to indoor mold and fungi can worsen asthma and respiratory issues. Medical practitioners can identify and manage these health effects, though further research is needed for long-term impacts.
Area of Science:
- Environmental Health
- Mycology
- Public Health
Background:
- Indoor air quality is a growing concern.
- Fungal and mold exposure are linked to various health issues.
- Understanding these effects is crucial for medical practitioners.
Purpose of the Study:
- To provide medical practitioners with current information on health effects of indoor fungi.
- To outline clinical evaluation methods for fungi-related health problems.
- To detail preventive strategies against indoor mold exposure.
Main Methods:
- Literature review of studies from 1985-2000.
- Searched MEDLINE using keywords: mould, fungus, indoor air, health effects.
- Analysis of case reports, case-control, and cross-sectional studies.
Main Results:
- Strong evidence links dampness and fungi to respiratory problems, including asthma exacerbation.
- Further research is necessary to confirm systemic, long-term, and infant pulmonary hemorrhage risks.
- Indoor fungal exposure poses public health risks, necessitating physician intervention.
Conclusions:
- Family physicians can recognize and manage health issues related to indoor fungi.
- Referral to appropriate resources is key for managing complex cases.
- Ongoing research will further clarify the full spectrum of health effects.
