3 History

1997-98: National Surveillance Program for Communicable Diseases (NSPCD) initiated

March, 2003: Central Surveillance Unit (CSU)

Nov, 2004: Integrated Disease Surveillance Project (IDSP)

2007-08: Making of IDSP as part of National Rural Health Mission (NRHM)

4 Public health Surveillance Surveillance is defined as the ongoing systematic

collection, collation, analysis and interpretation of data and dissemination of information to those who need to know in order that action be taken.

5 Public health Surveillance Surveillance is defined as the ongoing systematic

collection, collation, analysis and interpretation of data (disease / health event) and dissemination of information to those who need to know in order that action be taken.

Page 6: Integrated Disease Surveillance Project (IDSP)

6Why do we need to do surveillance? Recognize cases or cluster of cases to trigger intervention to prevent transmission or reduce

morbidity and mortality.

Identify high risk groups or geographical areas to target interventions and guide analytic studies.

Develop hypotheses that lead to analytic studies about risk factors for disease causation, propagation or progression.

Assess the public health impact of health events and measure trends.

Demonstrate the need for public health intervention programme and resources during public health planning.

Monitor effectiveness of prevention and control measures and prevent outbreaks.

7 Objectives of the Integrated Disease Surveillance Project. To establish a decentralized district based system of surveillance for

communicable and non-communicable diseases so that timely and effective public health actions can be initiated in response to health changes in the urban and rural areas.

To integrate existing surveillance activities to avoid duplication and facilitate sharing of information across all disease control programmes and other stake holders so that valid data is available for health decision making in the district, state and national levels

8 Classification of surveillance in IDSP

Syndromic Diagnosis made on the basis clinical pattern by paramedical personnel

and members of community Presumptive Diagnosis is made on typical history and clinical examination by medical

officers Confirmed Clinical diagnosis by medical officer and or positive laboratory

identification

Page 32: Integrated Disease Surveillance Project (IDSP)

05/01/2023

32 Need for private sector participation in disease surveillance Most patients (>70%) go to private sector Private physicians are the preferred first contact Private sector is more likely to detect early warning signs of outbreak Lack of public sector service provider especially in urban areas

54 Definition of an outbreak

Occurrence in a community of cases of an illness clearly in excess of expected numbers

The occurrence of two or more epidemiologically linked cases of a disease of outbreak potential constitutes an outbreak (e.g., Measles, Cholera, Dengue, Japanese encephalitis, or plague)

Page 55: Integrated Disease Surveillance Project (IDSP)

05/01/2023

55 Sources of information to detect outbreaks Rumour register

To be kept in standardized format in each institution Rumours need to be investigated

Community informants Private and public sector

Media Important source of information, not to neglect

Review of routine data Triggers

Page 56: Integrated Disease Surveillance Project (IDSP)

05/01/2023

56 Early warning signals for an outbreak

Clustering of cases or deaths Increases in cases or deaths Single case of disease of epidemic potential Acute febrile illness of an unknown etiology Two or more linked cases of meningitis, measles Unusual isolate Shifting in age distribution of cases High vector density Natural disasters

Page 57: Integrated Disease Surveillance Project (IDSP)

05/01/2023

57 Objectives of an outbreak investigation1. Verify 2. Recognize the magnitude 3. Diagnose the agent4. Identify the source and mode of transmission5. Formulate prevention and control measures

59 Basic responses to triggers

There are triggers for each condition under surveillance Various trigger levels may lead to local or broader response Tables in the operation manual propose standardized actions to take

following various triggers Investigations are needed in addition to standardized actions
