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.
INH 3 mg/kg for 6 months
INH 3 mg/kg for 6 months
INH 3 mg/kg for 3 months
INH 5 mg/kg for 3 months
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.
