The Integrated Disease Surveillance Programme (IDSP) is a nationwide disease surveillance system in India incorporating both the state and central governments aimed at early detection and long term monitoring of diseases for enabling efficient policy decisions. It was started in 2004 with the assistance of the World Bank. A central surveillance unit has been set up at the National Centre for Disease Control in Delhi. All states, union territories, and district headquarters of India have established surveillance units. Weekly data is submitted from over 90% of the 741 districts in the country. With the aim of improving digital surveillance capabilities, the Integrated Health Information Platform (IHIP) was launched in a number of states in November 2019.
