Tuberculosis and New Entrant Assessment Team

The Tuberculosis and New Entrant Assessment Team support patients with tuberculosis disease (TB) and their families. We offer TB screening to people who have been in contact with someone with TB and to those from a country with a high rate of TB. We also administer the Bacillus Calmette–Guérin (BCG) vaccination, which is used to protect against TB, to children who missed it at birth.

We are a small, friendly team based in York. We cover North Yorkshire, providing support and preventative measures to those at risk of TB and latent TB infection.


Tuberculosis is a bacterial infection caused by a germ called Mycobacterium Tuberculosis. TB is spread through the inhalation of tiny droplets from the coughs or sneezes of a person with TB disease. Whilst TB mainly affects the lungs, the infection can spread to other parts of the body.

Not everyone infected with TB bacteria becomes sick. As a result, two TB-related conditions exist: latent TB infection and TB disease.

The general symptoms of TB disease include:

  • Unexplained weight loss
  • Loss of appetite
  • Night sweats
  • Fever
  • Fatigue
  • Swollen glands

Symptoms of TB of the lungs also include:

  • Coughing for three weeks or longer
  • Coughing up blood
  • Chest pain
  • Shortness of breath

Other symptoms depend on the part of the body that is affected.

Latent TB infection

People with latent TB infection do not feel sick and do not have any symptoms. They are infected with Mycobacterium Tuberculosis but do not have the disease as their immune system is keeping it dormant. The only sign of TB infection is a positive reaction to the Mantoux test or TB blood test.

People with latent TB infection are not infectious and cannot spread TB infection to others.

Without treatment, about 10 per cent of people with latent TB infection will develop TB disease at some point in their lives. About half of those people develop TB disease in the first two years of infection. This figure is higher for people who have a weakened immune system, and especially for those with HIV infection.

Both latent TB infection and TB disease can be treated with specific antibiotics. Treatment for TB is completely free.

TB screening

If you have been in close contact with a person with TB disease and you’re at risk of catching the TB infection, you will be contacted to arrange a screening.

If you were born in a country where TB disease is more common, you will be offered screening when you arrive in the UK. This may be in addition to any screening you had as part of a visa application.

You may be offered one or more or the following tests to identify if you have been infected with TB but have not yet developed symptoms:

  • Mantoux skin test (involves injecting a substance called PPD tuberculin into the skin of your forearm)
  • TB blood test (IGRA)
  • HIV blood test
  • Chest X‐ray

The results of your test(s) will determine what advice or treatment is best for you.

If any of the above affect you or you wish to discuss anything related to TB, New Entrant Screening or the BCG vaccination please contact the TB Team direct on 01423 555734 or email


We accept referrals from any route, including via GPs. However it is often quicker to contact the team directly, and we would be very happy to talk to you.
