What is Surveillance
• Systematic, ongoing…
– Collection
– Analysis
– Interpretation
– Dissemination
• …of health outcome data
Health action
• investigation
• control
• prevention

Why we do surveillance
Estimation the size of health problem
Detection of outbreaks
Characterize disease trends
Evaluate interventions and preventive programmes
Provide information for health planning and financing
Identifying training needs in terms of categories and levels
Identify and prioritize research needs

Syndromic Surveillance
“Syndromic surveillance” is defined as the collection and analysis
of “health-related data that precede diagnosis and signal with
sufficient probability of a case or an outbreak to warrant further
public health response”

Surveillance Focus
Risk factor surveillance - for estimation and Prevention
Actual Burden of Diseases
– Hospital records (HMIS)
– Mortality Statistics (Verbal Autopsy)
– Insurance data
– Funeral Services
– Drug Data

Universal Health Coverage
Universal Health Coverage – is defined as ensuring that all people
can use the promotive, preventive, curative, rehabilitative and
palliative health services they need, of sufficient quality to be
effective, while also ensuring that the use of these services does not
expose the user to financial hardship.
