Types of Surveillance
Disease surveillance is the collection,
analysis, and interpretation of data to
determine disease trends and patterns.
Disease surveillance provides information
such as:
- Disease incidence, morbidity, and mortality, and progress in achieving disease control goals
- Changes in patterns of morbidity and mortality
among different age groups in different deographical
areas and among different economic, social, or cultural
groups
- Impact of immunization strategies on disease incidence
- Disease trends
The overriding value of disease surveillance, however, is its use as
a tool to identify the presence of infectious diseases
and guide actions to prevent them
from becoming threats to public health. The following describes the activities
required to carry out that function.
Facility-Based Routine Surveillance
Community-Based Surveillance
Sentinel Surveillance
