Figure: Deriving the Annualized TB Case Notification Rate
The National TB Elimination Program calculates TB notification rates based on TB cases notified using the digital surveillance system called Nikshay. Each state/district is provided with an annual target for TB case notification, the progress of which is measured periodically to understand efforts taken for the detection of TB cases.
