One of the main components of the End TB Strategy is the need for infection
prevention and control (IPC) in health facilities and other settings where the risk of
transmission is high. The strategy has three components that should be implemented as
an integrated package of IPC interventions to prevent M. tuberculosis transmission.
The main components of the policy are a) administrative controls, b) environmental
controls, and c) respiratory protection. The administrative controls include the triage of
patients with signs or symptoms or with known TB disease, the isolation of patients
with presumed or demonstrated TB, and the prompt initiation of effective
antituberculosis treatment for patients diagnosed with tuberculosis. The environmental
controls include the use of upper-room germicidal ultraviolet (GUV) and natural o
mechanical ventilation systems to reduce the concentration of infectious particles in the
air. Finally, the respiratory protection strategy recommends using particulate respirators
integrated as a part of a respiratory protection protocol.
Another essential component of the strategy is the periodic screening of all health
workers with a risk of exposure to tuberculosis patients.
