Integrated Disease Surveillance Programme (IDSP)


To strengthen the disease surveillance in the country by establishing a decentralized State based surveillance system for epidemic prone diseases to detect the early warning signals, so that timely and effective public health actions can be initiated in response to health challenges in the country at the Districts, State and National level.

Mandate / Objectives

  • Integration and decentralization of surveillance activities through establishment of surveillance units at Centre, State and District level. 
  • Human Resource Development – Training of State Surveillance Officers, District Surveillance Officers, Rapid Response Team and other Medical and Paramedical staff on principles of disease surveillance. 
  • Information Communication Technology - for collection, collation, compilation, analysis and dissemination of data. 
  • Strengthening of public health laboratories.

Brief History

Nationwide Integrated Disease Surveillance Programme (IDSP) was launched with World Bank assistance in November 2004 to detect and respond to disease outbreaks quickly. The project was extended for 2 years in March 2010 i.e. from April 2010 to March 2012, World Bank funds were available for Central Surveillance Unit (CSU) at NCDC & 9 identified states (Uttarakhand, Rajasthan, Punjab, Maharashtra, Gujarat, Tamil Nadu, Karnataka, Andhra Pradesh and West Bengal). 
District Surveillance Unit (DSU)) have been established in July 2007 at Barasat, North 24 Parganas district. Basirhat DSU segregated under Basirhat Health District in October 2017 to working in full-blown.

  • Training of District Surveillance Team and Rapid Response Teams (RRT) has been completed. 
  • Online reporting for data entry, training, video conferencing and outbreak discussion.
  • Weekly disease surveillance data on epidemic prone disease are being collected from reporting units such as SC/PHC/BPHC/RH including government and private-sector hospitals.  The data are being collected on ‘S’ syndromic; ‘P’ probable; & ‘L’ laboratory formats using standard case definitions. Presently 100% blocks report such weekly data through e-mail/portal ( The weekly data are analyzed by DSU for disease trends. Whenever there is rising trend of illnesses, it is investigated by the RRT to diagnose and control the outbreak.
