<prompt> 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 mgkg for 6 monthsINH 3 mgkg for 6 monthsINH 3 mgkg for 3 monthsINH 5 mgkg for 3 months  <response>: Here since the child is asymptomatic and Mantoux test is not available, INH 5 mgkg 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.
