General concepts on TB infection control. Presentation outline. Transmission of TB Hierarchy of Infection Controls Administrative Infection Controls Environmental Controls Personal Respiratory protection HCW protection. The purpose of infection control Program.
- infection control
- hospital epidemiology
All settings should perform risk classification as part of risk assessment to determine need for and frequency of an HCW testing program, regardless of likelihood of encountering persons with TB disease.
Technologies for removing or inactivating M. tuberculosis consist ofLocal exhaust ventilation, General ventilation
Air-cleaning methods, e.g., high-efficiency particulate air (HEPA) filtration, ultraviolet germicidal irradiation (UVGI)
In places with highest risk of infection
Use of filters
Replacement of filter depends on:
- volume and type of exposition
- environmental condition
- Airflow rate
- type of filter
- place of ventilation system
