Hypersensitivity pneumonia is characterized by flu-like symptoms, including fever. Newer energy efficient HVAC systems that reduce the outdoor-indoor air exchange and custodial work involving cleaning product vapors and disturbed dust during work hours add to the problem. Communication within the organization is also critical to address air quality concerns. Open discussion that uncovers the history and pattern of reported problems, including factual and emotional components, provides the basis for proper investigation and remedies. These contribute to poor fresh air exchange, relatively high humidity, and fungal growth.
Air quality is an appropriate topic for the school health advisory council.
