What aspect of building conditions can lead to illness according to the CDC?

Poor indoor air quality is recognized by the CDC as a significant factor that can lead to various health issues among occupants of a building. When indoor air is contaminated with pollutants such as mold, allergens, volatile organic compounds (VOCs), carbon monoxide, and other harmful substances, it can contribute to respiratory problems, allergic reactions, and other health complications. Good indoor air quality is essential for ensuring a healthy and safe living or working environment.

In contrast, while temperature fluctuations can impact comfort and sometimes lead to stress on the body, and structural integrity is critical for safety, they are not directly linked to illness in the same way that air quality is. Accessibility issues relate more to the ability of individuals to safely navigate physical spaces and do not inherently cause illness. Thus, addressing indoor air quality is vital for maintaining public health.
