There is a gap in TB cases registered and those opting for directly observed treatment (DOT) at civic or state hospitals. MUMBAI: The number of Mumbaikars dropping out of TB treatment (DOTS) increased from 12% in 2013 to 15% in 2017, according to data released by NGO Prajay. The NGO’s white paper reported that TB cases increased to 55,130 in 2017-18, a 33% jump from 2013-14.Praja brings out an annual health report, analyzing data gathered from BMC’s health department, using RTI. Also, if BMC numbers are anything to go by, dengue cases seem to have remained consistent over years. Confirmed cases reported by BMC are nowhere close to data collated by the non-profit.
