You are the only medical officer of a PHC in a remote tribal area of Rajastan. You had staed Category-I DOTS for a 23 year old woman who is the mother of a 2 year old child. What chemoprophylaxis will you recommend for the child in this scenario? Note that the child is asymptomatic and Mantoux test is not available.
Here since the child is asymptomatic and Mantoux test is not available, INH 5 mg/kg should be given for 6 months. If Mantoux test was available, the child would have been given chemoprophylaxis for 3 months following which a Mantoux would have been done.If the induration was > or = 6 mm chemoprophylaxis would have been given for another 3 months but if the induration was lesser than 6 mm then the chemoprophylaxis would have been discontinued.
