 Hello everyone, I am Dr. Archana, I am the Associate Consultant, Infectious Disease Specialist at Manipal Hospital, Oral Airport Road, Bangalore. Tuberculosis can be caused mainly by inhalation, that is, when a child comes in contact with an adult having active tuberculosis, especially in a household. So the child has to be in close contact with an adult in the household majority of the times and the other possibility is in the school premises also. The other way of getting tuberculosis in children is something birth itself, that is called as congenital tuberculosis, where the child gets tuberculosis when the child is in the womb of the mother itself, if the mother is having active tuberculosis and has been not treated for the same during her duration of pregnancy or at the time of delivery. These are the two ways in which a child can get tuberculosis.
