The symptoms can be clinically defined and have clearly identifiable causes.Building occupants complain of symptoms such as cough chest tightness fever, chills and muscle aches.Indicators of Building Related Illness include: Some complainants report relief soon after leaving the building, others continue to have continuing symptoms and illness.Mold-induced respiratory allergies and research on Alternaria both have a lengthy history: the first was described as early as 1698 and the second dates back to 1817. The cause of the symptoms is not known. Alternaria may also be found in damp, insufficiently ventilated houses, where its allergenic properties cocreate the sick building syndrome.

Building occupants complain of symptoms associated with acute discomfort, e.g., headache eye, nose, or throat irritation dryĬough dry or itchy skin dizziness and nausea difficulty in concentrating fatigue and sensitivity to odors.

Indicators of Sick Building Syndrome include: Frequently, problems result when a building is operated or maintained in a manner that is inconsistent with its original design or prescribed operating procedures, or a indoor water leak has taken place. On occasion this condition is temporary, but some buildings have long-term problems. In contrast, the term “ building related illness” (BRI) is used when symptoms of diagnosable illness are identified and can be attributed directly to airborne building contaminants.Ī World Health Organization Committee report suggested that up to 30 percent of new and remodeled buildings worldwide may be the subject of excessive complaints related to indoor air quality and sick building syndrome.

The complaints may be localized in a particular room or zone, or may be widespread throughout the building. HVLS fans, mold remediation, and thoughtful selection of materials during renovations can help to clear up or prevent sick building syndrome problems. This last study was done with enough mold exposed individuals to allow for the statistical significance of SC exposure to be evaluated.The term “ sick building syndrome” (SBS) is used to describe situations in which building occupants experience acute health and comfort effects that appear to be linked to time spent in a building, but no specific illness or cause can be identified.

Finally, we were able to demonstrate the presence of MTM in the sera of individuals who had been exposed to SC in indoor environments. Following that study, we next showed that the same phenomenon actually occurred in SC infested buildings where people were complaining of health problems potentially associated with SBS. We then showed, in a laboratory study, that the MTM of SC can become airborne attached to spores or SC particulates smaller than spores.

We next showed that PC when inhaled, can release in vivo, a protease allergen that can cause a significant allergic inflammatory reaction in the lungs of mice. We then showed that SC and Penicillium chrysogenum (PC) colonies remain viable long after a water source has been removed, and the MTM produced by SC remain toxic over extended periods of time. In these studies we showed that the macrocyclic trichothecene mycotoxins (MTM) of Stachybotrys chartarum (SC) are easily dissociated from the surface of the organism as it grows and could therefore be consequently spread in buildings as the fungus experiences additional water events.

Fungal infection is especially a risk factor for immunodeficient patients, but it occurs in immunocompetent patients as well.
