 Hello everyone, I am Dr. Archana, I am the Associate Consultant, Infectious Disease Specialist at Manipal Hospital, Oral Airport Road, Bangalore. Tuberculosis can be prevented by giving the vaccine known as BCG at the time of birth. This vaccine has efficacy of around 80% in preventing the most fatal form of tuberculosis that is the disseminated tuberculosis which is called as milliary tuberculosis and the TB meningitis which are common in the less than 2 years of age. Suppose if the child was not given the BCG vaccine at birth, a catch up vaccination can be done till the age of 5 years. The other way of prevention which can be done is if a child is exposed in a household to an adult with active tuberculosis, the child has to be screened for tuberculosis and if the child doesn't show an tuberculosis disease then the child has to be given an anti tubercular profile access with a single drug for a duration of 6 months. Also tuberculosis is more rampant when HIV infected children. In these children the tuberculosis disease stage has to be found out if they are not infected or if they are not deceased then again profile access for these children also is recommended for a duration of 6 months with a single drug.
