Tuberculosis in children
Tuberculosis (TB) is a disease caused by a germ called Mycobacterium tuberculosis.
It usually affects the lungs and is caught from other people. Babies and young children are more at risk of infection because their immune systems are not fully developed. In countries where there is a lot of TB, children are more likely to get more severe or life-threatening forms of TB. This is not the case in the UK.
It can also be more difficult to diagnose TB in children because lots of the signs of TB can also be signs of other diseases.
