Five-years experiences of the revised national tuberculosis control programme in northern part of Kolkata, India

Abstract

A steady increase was observed in the annual total case detection rate and annual new smear-positive case detection rate from 2001 to 2005, but the 3-month conversion rate and cure rate of new smear-positive patients were progressively decreased. Default rate and treatment failure rate of new smear-positive patients were also increased. So it needs extra attention and evaluation of this disappointing treatment outcome.
