The increase in the drop out rate of tuberculosis patients during treatment and a rise in treatment failures is adding to India's multi-drug resistant TB cases. Drug resistance occurs when patients are not treated with standard treatment protocols or when they discontinue treatment. Presenting the India TB Control Report Card to media persons on World TB Day here today, Dr Bobby John, president of Global Health Advocates, said, "The aim of the National TB Control Programme is to deliver 85 per cent cure among people presenting themselves for cure. People are dropping out of treatment. They are defaulting. We have to make sure that defaulters are reduced. Of the 8,80,000 people, who were put on treatment between January and December 2007, 6.1 per cent dropped out, according to data compiled by the National TB Control Programme. At the end of six months treatment, a sputum test is mandatory. The data shows that 2.2 per cent did go through any sputum test at the end of six months.'
