Sick Building Syndrome (SBS) is best described as?

• A. An illness where no disease or cause can be identified, yet acute health effects are linked to time spent in a building. Symptoms are nonspecific and include eye, skin, and airway irritation, as well as headache and fatigue.
• B. A disease caused by mold exposure leading to chronic lung issues.
• C. A short-term allergic reaction from outdoor air pollution only.
• D. A respiratory infection spread within office spaces.

Answer: (A)

Sick Building Syndrome describes ill health effects that appear to be linked to time spent in a building but for which no specific disease or single cause can be identified. The symptoms are nonspecific and commonly involve irritation of the eyes, skin, and airways, plus headaches and fatigue. A defining feature is that these symptoms tend to improve when you leave the building, indicating an issue with indoor environmental quality rather than a defined illness. This differs from mold exposure causing chronic lung issues, which implies a specific health condition with a known cause, from outdoor air pollution triggering a short-term allergic reaction, which has a distinct external trigger, and from a contagious respiratory infection spreading in an office.
