Detailed explanation-1: -BCG vaccine is recommended at birth or after completion of prophylaxis (3-6 months) in all neonates.
Detailed explanation-2: -Chemoprophylaxis of tuberculosis may be primary or secondary. Primary chemoprophylaxis is intended for infants and children with negative tuberculin tests and exposed to contagion, in order to avoid primary tuberculosis.
Detailed explanation-3: -Alternative treatments for latent TB infection in children include 4 months of daily rifampin or 9 months of daily isoniazid.
Detailed explanation-4: -If isoniazid cannot be used, 6–9 months of rifampicin, pyrazinamide and ethambutol can be considered. If pyrazinamide is discontinued before the patient has completed the intensive phase, the total duration of isoniazid and rifampicin therapy may be extended to 9 months (7).
