ENVIRONMENTAL CONTROL FOR TUBERCULOSIS: BASIC UPPER-ROOM ULTRAVIOLET GERMICIDAL IRRADIATION GUIDELINES FOR HEALTHCARE SETTINGS
Tuberculosis (TB) is a severe, contagious disease that primarily affects the lungs. It is usually transmitted from person to person via airborne particles that contain TB bacteria. ne of the major concerns for healthcare workers is the potential for transmission of TB at worksites from undiagnosed or unsuspected cases. Upper-room ultraviolet germicidal irradiation (UVGI) systems are considered a supplement or adjunct to other TB
infection-control measures (e.g., ventilation) in settings where persons with undiagnosed TB could potentially contaminate the air (e.g., waiting rooms, emergency rooms, corridors, central areas).
