SA2 Flashcards
disease that occurs infrequently and irregularly
Sporadic
usual prevalence of a disease or infectious agent in a population within a geographic area
Endemic
increase often sudden in the number of cases of a disease above what is expected in that
population in that area
epidemic
epidemic that has spread over several countries or continents
PANDEMIC
same as the epidemic but is often used for a more limited geographic area
outbreak
aggregation of cases grouped in a place and time that are suspected to be greater than the
number expected
cluster
pathogen: a virus, bacterium, parasite, or other microbe
agent
human who can get the disease
host
extrinsic factors that affect the agent and the opportunity for exposure.
environment
-the problem is subclinical or hidden from view
The iceberg principle
shows the relationship between multiple factors that contribute to the cause
Web Causation
-vital in identifying risk factors and monitoring health disease conditions in the population
Screening and Surveillance
process of detection for disease or disorders among healthy people.
Screening
systematic, on-going and analytic process of monitoring to scrutinize disease
- involves investigating the distribution and possible cause of disease
surveillance
CATEGORY OF SURVEILLANCE
rapid detection, notification, verification, and assessment of public events
Event Based
CATEGORY OF SURVEILLANCE
routine reporting of cases of disease such as notifiable disease surveillance
system
Indicator based
Level of prevention
prevent even before the risk factor is present
Healthy Lifestyle and avoiding the development of behaviors and exposure patterns
Primordial prevention
level of prevention
control of exposure to risk factors, before the disease development.
promote healthy lifestyle and environment Health Protection aimed at reducing the risk for specific
diseases
Primary Prevention
Level of prevention
to detect early the disease before the onset of signs and symptoms.
Examples: Mammography to detect possible cancer
Secondary prevention
Level of prevention
Managing the disease after the diagnosis to slow or stop disease progression
Chemotherapy, Rehabilitation and Screening for complication
Tertiary Prevention
Examines relationship between health problems and other variables of
interest as they exist in a defined population at one particular time.
Cross Sectional Study
– a longitudinal study.
-disease free in the beginning of the study.
Cohort Study
retrospective study
-Subjects positive for disease or health condition (called the “case” group) are compared with subjects
who are negative or have no disease or health condition (called the “control” group)
Case Control Study
understand the quality and the amount of influence that determinants have on the occurrence of
disease
Analytical Epidemiology
to confirm a casual relationship suggested by observational studies.
Experimental epidemiology
Microorganisms, such as bacteria, viruses, fungi, or parasites, that can cause
infectious disease.
Infectious agent
The host in which infectious agents live, grow, and multiply
Reservoir
The route by which an infectious agent escapes or leaves the reservoir.
Portal of exit
Immediate transfer from Person to Person
Direct
Vector Borne (Insects / Animals) / Vehicle (Fomite)
Indirect
Can remain suspended in the air for a period of time
Airborne
