While not recommended as a general screen, screening for tuberculosis is usually recommended based on known risk factors.
In the UK, the number of TB cases is rising. Alcoholics, HIV-positive individuals, some recent immigrants and healthcare workers are at increased risk. The disease is most commonly found in places such as hostels for the homeless, prisons, and centres for immigrants arriving from areas with high rates of HIV infection or inadequate health provision.
Typically, you may not feel ill or have symptoms. If you are at risk of infection, for example you have come into contact with a person infected with tuberculosis, are HIV-positive or receiving immunosuppressive therapy, you may be given a tuberculin (Mantoux) skin test, a chest X-ray and sample of sputum or phlegm may be taken for laboratory examination.
It is recommended by the Health Protection Agency that individuals working as healthcare workers who are previously unvaccinated, and who are negative or grade 1 on tuberculin testing, should receive BCG vaccination.
