Hospital infection control practices for tuberculosis.

Although completely eliminating the risk for transmission of M. tuberculosis in all health-care facilities may not be possible, adherence to the principles outlined in the CDC guidelines should reduce the risk to persons in such settings. The guidelines are designed to help health-care facilities develop an infection-control plan tailored to the individual circumstances and risk in each facility. The key to maintaining an effective TB infection control plan is periodic evaluation of the plan, with reassessment of risk and revision of the plan accordingly.
