Surveillance Flashcards
Components of Foodnet
Active laboratory based surveillance
Survey of clinical laboritories, physicians and general population
Epidemiologic studies
Cons of active surveillance
Very expensive, labor intensive
Usually done once or intermittently
Sometimes may not be a good representative of the population
Active Surveillance
Involves the committed effort of the veterinary / health authority to identify subjects for data or samples
Cons of targeted surveillance
May not be representative of the population
Objectives of Foodnet
- Determine the burden of foodborne illness in the US
- Monitor trends in the burden of specific foodborne illness over time
- Attribute the burden of foodborne illness to specific foods and settings
- Disseminate information that can lead to improvements in public health and the developement of interventions to reduce the burden of foodborne illness
Dead animals, treatment of sick animals and lost productivity are examples of (direct/indirect) costs.
Direct
Response
Immediate response to disease outbreaks and events is considered part of surveillance
Passive Surveillance
Subission is initiated by and at the discretion of the sample/data provider - veterinary and health authority does very little to select subjects for sampling or information
Cons of Passive Surveillance
Little control over who provides data/samples
Not a representative sample of the population
Won’t work for less valued animals that don’t use veterinary services
If disease is stigmatized farmers won’t report
Types of Surveillance
Passive Surveillance
Active Surveillance
Sentinel Surveillance
Targeted Surveillance
CDC Program
Tracks health problems as they evolve and provide public health officials with data, information and tools
Prepare and coordinate responses to safeguard and improve the health of the american people
BioSense
Cons of sentinel surveillance
May not be representative of the population
Most common type of surveillance
Passive Surveillance
Sentinel Surveillance
Small group is monitored as an indicator of the greater population health or disease risk
Pros of Sentinel surveillance
Less expensive than monitoring the whole population
Often the only method available
Allows intensive, multiple testing - early warning
