Which of the following is an example of a building-related illness (BRI) associated with indoor air quality problems?

Building-related illness happens when health effects arise from exposures inside the built environment, often through inhaling contaminants or aerosols released by building systems. Legionella fits this pattern because it can colonize building water systems—like cooling towers, showers, and hot water tanks. When these systems aerosolize contaminated water, tiny droplets containing the bacteria can be inhaled by occupants, leading to Legionnaires’ disease or Pontiac fever. This makes it a classic example of a BRI tied to indoor air and water system conditions. Influenza is mainly spread from person to person through droplets and contact, not typically linked to a building’s air quality or water systems. E. coli is usually associated with ingestion of contaminated food or water rather than inhalation of indoor air. Mold spores are indeed related to indoor air quality issues and can cause allergies or hypersensitivity pneumonitis, but Legionella is the most singled out example of a building-related illness connected to IAQ issues through aerosol exposure from building systems.
