Adequate ventilation in healthcare facilities is essential for preventing transmission of airborne infections, and is strongly
recommended for controlling spread of TB. The choice of ventilation system will be based on assessment of the facility and
informed by local programmatic, climatic and socioeconomic conditions (refer to guideline for Controls 10a and 10b). Any ventilation system
must be monitored and maintained on a regular schedule. Adequate resources (budget and staffing) for maintenance are
critical.
