Agartala/Aizawl, March 24 (IANS) On an average, five percent of tuberculosis (TB) patients die each year in India's northeastern region, an expert said on Thursday. "On an average, five percent of the total TB patients die in northeast India every year. The national average is also the same," TB expert Babul Das told IANS. Das, who has attended many national and international scientific and medical events on TB, while quoting the World TB report 2015, said India continues to account for 23 percent of the global TB burden. "Each year, about 2.2 million people develop TB in India and an estimated 220,000 (rpt 220,000) people expire due to the disease which clearly explains that more steps must be taken to check the ailment," he said. The expert said that in most cases, due to lack of awareness and treatment, TB turned into cancer and HIV-positive, and many patients also die of a heart attack.
