PHLS work on the surveillance and epidemiology of tuberculosis.

The re-emergence worldwide of tuberculosis as a major threat to public health and continuing and changing challenges in the control of tuberculosis in England and Wales provide the basis for the designation, by the PHLS, of tuberculosis as a priority area. In addition to the mycobacteriology reference services provided by the PHLS in England and Wales (summarised in an accompanying article) the PHLS contributes to the control of tuberculosis through its surveillance and other epidemiological work. This article summarises the range of this work, emphasising the collaborative nature of the effort required for surveillance, prevention, and control of tuberculosis.
