Integrated Disease Surveillance Project (IDSP) – Objectives, Components, Syndromes under surveillance, Reporting units

Integrated Disease Surveillance Project (IDSP) is a decentralised state based surveillance system in India.


  • Identification of cases and cluster of cases that are of public health importance
  • Prevention of further transmission of disease
  • Limiting mortality and morbidity
  • Assessment of public health importance
  • Analysis of trends
  • Demonstrate the importance of public health interventions
  • Allocate funds for healthcare
  • Monitoring of preventive and control measures
  • Identification of risk factors and developing hypothesis
  • Identification of high groups and geographical areas

Integration is an important component of IDSP. The various aspects of Integration include:

  • Partnership between health and non-health sectors
  • Collaboration with private groups and NGO’s
  • Sharing of disease surveillance data

Components of surveillance:

  • Collection of data
  • Compiling of data
  • Data analysis and interpretation
  • Follow up action
  • Feedback

Types of surveillance under IDSP:

  • Syndromic diagnosis – by health worker / community workers – based on identification of a collection of symptoms
  • Presumptive diagnosis – by medical office based on history and clinical examination
  • Confirmed diagnosis – history and clinical examination by medical officer with laboratory testing

Clinical syndromes under surveillance:

  • Fever – Malaria, Typhoid, Dengue, Japanese Encephalitis, Measles
    • lasting for less than 7 days without localising signs
    • with rash
    • with altered sensorium or convulsions
    • with bleeding from skin or mucous membrane
    • lasting for more than 7 days with or without localising signs
  • Cough lasting for more than 3 weeks – Tuberculosis
  • Acute flaccid paralysis – Polio
  • Diarrhoea – Cholera
  • Jaundice – Hepatitis, Malaria, Leptospirosis, Yellow fever
  • Unusual syndromes – Anthrax, Plague, Emerging epidemics

Core conditions under surveillance:

  • Regular surveillance
    • Vector borne disease – malaria
    • Water borne disease – acute diarrhoeal disease, typhoid
    • Respiratory disease – Tuberculosis
    • Vaccine preventable disease – measles
    • Diseases under eradication – Polio
    • Other conditions – Road Traffic Accidents (linked with police computers)
    • International commitments – Plague
    • Unusual clinical syndromes – Meningoencephalitis, respiratory distress, haemorrhagic fevers
  • Sentinel surveillance
    • STD’s – HIV, HBV, HCV
    • Water quality monitoring
    • Outdoor air quality  monitoring (large cities)
  • Regular periodic surveys – for non communicable disease (NCD) risk factors
    • Anthropometry
    • Physical activity
    • Tobacco
    • Nutrition
    • Blood pressure
  • Additional state priorities – Each state may include up to 5 additional diseases based on local needs

Reporting units for disease surveillance:

  • PHC’s
  • CHC’s
  • District hospitals
  • ESI hospitals
  • Medical college hospitals
  • Private medical practitioners
