15 Surveillance and Response Flashcards
Functions of surveillance system
Early warning system
Document impact of intervention
Monitor epidemiology of health problems
Functions of disease surveillance
Predict, observe, and minimize harm
Increase knowledge of contributing factors
Monitor morbidity/mortality
Inform public of hazard
Types of surveillance
Passive (wait for reports)
Active (cellect or seek
Sequence of events when the agent leaves it reservoir or host through a portal exit, is conveyed by some mode of transmission, and enters through an appropriate portal of entry to infect a susceptible host
Chain of infection
Habitat in which the agent normally lives, grows, and multiplies
Reservoir
Path by which a pathogen leaves its host; usually the site where the pathogen is localized
Portal of exit
The means by which an infectious agent is passed on to a host
Mode of Transmission
The manner in which a pathogen enters a host
Portal of Entry
The target of infectious agent; dependent on genetic, constitutional factors, and immunity of the host
Susceptible host
Types of surveillance systems
Case based (routine collection) Event based (receive reports) Laboratory based (criteria)
Disease required by law to be reported to government authorities
Notifiable disease
Prioritization of diseases
High impact of disease High communicability Preventability Response capacity Public interest
FHSIS
Network of information (DOH and LGU)
For managing health facilities
For monitoring health programs and nationwide delivery
Sentinel surveillance (NESSS)
Active hospital-based surveillance
Case definition
Clinical case definition Laboratory criteria Case classification (clinically confirmed, probable, laboratory confirmed)
