Tuberculosis (TB)

Tuberculosis infection control

Prevention of new infections of Mycobacterium tuberculosis is critical to reduce the burden of disease caused by TB. There are various factors that determine the risk of transmission of tuberculosis, but an increased likelihood of transmission is observed in households of TB patients. In the past, TB infection control in health-care facilities and congregate settings was largely neglected. However, given the high potential for transmission and progression to disease in such settings, and the risk posed for all TB control efforts, global policies were required. In this regard, the WHO issued an evidence-based policy for the implementation of sound infection control by all stakeholders in these settings.

Key topics

TB infection control is a combination of measures aimed at minimizing the risk of TB transmission within populations. The recommended set of activities for national and subnational TB infection control is necessary to facilitate implementation of preventive measures in health-care facilities, congregate settings and households.
