A significant proportion - about 15% to 20% - of all tuberculosis (TB) occurs in children in India, where paediatric TB is a serious, but under-recognized and neglected public health problem. "The reason is that, unlike in adults, children get forms of TB that are not infectious. Therefore less public health priority and importance is given to it. TB spreads through the air borne route. So children get it from adults through cough etc. The most important risk factors in children are malnutrition, poverty, environmental pollution, poor housing, overcrowding, indoor air pollution, passive smoking, and to a much smaller extent HIV infection also" said Dr Soumya Swaminathan, National Institute for Research in Tuberculosis, Chennai.
