Tuberculosis (TB): diagnosis, screening, management and data

Information on the diagnosis, screening, epidemiology and public health strategy for tuberculosis and other mycobacterial diseases.

Introduction to tuberculosis (TB)

Tuberculosis (TB) is an infectious disease caused by bacteria from the Mycobacterium tuberculosis complex, which includes:

  • M. tuberculosis
  • M. africanum
  • M. bovis
  • rare species such as M. canetti, M. caprae, M. microti, and M. orygis

TB mainly affects the lungs but can involve almost any part of the body. It is spread through the air when a person with active TB in the lungs or throat coughs, sneezes, or speaks, releasing bacteria into the air that others can inhale.

Common symptoms of TB include:

  • persistent cough (lasting more than 3 weeks)
  • coughing up blood or sputum
  • a high temperature and/or night sweats
  • unexplained weight loss
  • feeling tired or exhausted

It can be treated with specific antibiotics but can be serious if not treated.

For more information and seeking advice if you have symptoms, visit the NHS tuberculosis page.

In the UK, TB is a notifiable disease, meaning all suspected or confirmed cases must be reported to public health authorities within 3 working days.

Public health approaches to TB prevention and care

See the BCG vaccination programme for further information including guidance, training and patient data pathways on vaccination and Severe Combined Immunodeficiency (SCID) screening.

Epidemiology and surveillance data of TB in the UK

The UK Health Security Agency collects real-time tuberculosis (TB) surveillance using the web-based national TB surveillance system (NTBS). This includes laboratory data on TB drug sensitivity, species and genomic relatedness (how similar TB bacteria are in samples from different people).
