TB can affect babies and children of any age, but it most often affects young children aged between one and four, as they have weaker immune systems.  However, children with TB are usually less infectious than adults, and so are less likely than adults to spread TB bacteria to other people.


With regards to the symptoms - your doctor may want to test your child for TB if he or she has had a cough for more than two weeks that won't go away; has swollen lymph glands; has a fever, particularly at night; is not gaining weight or is losing weight; has lost his appetite and also if they have recently been in contact with someone who has TB.
