How valid is the policy of adding Streptomycin for re-treatment cases?
Ans: Only a proportion of patients put on re-treatment regimen are failure cases and likely to be resistant to one or more drugs. Cohort analysis of patients treated so far in our country shows that two-thirds of the patients remaining smear positive after 5 moths of treatment on Cat I and subsequently treated with Cat II have been successfully treated.

Efficacy of twice weekly (TW) regimen has been demonstrated in many trials.
