EPIDEMIOLOGY Flashcards
Concerned with the course of disease in an individual
patient
Primary Care Physician
is a public health scientist, who is
responsible for carrying out all useful
and effective activities needed for
successful epidemiology practice
Epidemiologist
Goals of the epidemiologist
To limit disease, injury, and death
in a community by intervening
to prevent or limit outbreaks or epidemics
of disease and injury
study of the distribution and determinants of health related states or events in specified population and the application of this study to control health problems
Epidemiology
anything that affects the well-being of a population
Health-related states or events
• “Father of Medicine”
• Suggested the relationship between
the occurrence of disease & the
physical environment (300 B.C.)
Hippocrates
– Few advances in epidemiology – Epidemics
Plague, leprosy, smallpox, malaria, syphilis, yellow fever

3 Types of Epidemiology
- Descriptive epidemiology
- Analytical epidemiology
- Experimental epidemiolog
This type of epidemiology describes the distribution of health status in
terms of: age, gender, race, geography, time
etc.
Descriptive Epidemiology
What type of epidemiology studies of the determinants (causes) of
health-related states or events
Analytical Epidemiology
What type of epidemiology evaluates the effects of intervention
Experimental Epidemiology
This is kind of epidemiology is assessing health status, health
problems, health needs through
collections & surveys
Descriptive Epidemiology
Answers: why and how
Analytical Epidemiology
What type of epidemiology identifies the cause of a disease
Experimental Epidemiology
The disease surveillance of this type of epidemiology is this: • what (case definition) • who (person) • where (place) • when (time), and • how many (count)
Descriptive Epidemiology
What field of epidemiology tests hypotheses about relationships between health problems & possible risk factors, factors that increase that increase the probability of disease
Analytical Epidemiology
This type of epidemiology determines the effectiveness of a
vaccine, therapeutic drug, or surgical
procedure
Experimental Epidemiology
Classes of research questions
- occurrence
- (causal effects, etiology
- diagnostics
- intervention
effects - prognosis
- patient
experiences
any susceptible organism invaded by
an agent
HOST
the element that must be
present in order for disease to occur
AGENT
– includes all factors –
physical, biological, or social – that inhibit or
promote disease transmission
ENVIRONMENT
Influenced by exposure, susceptibility or
response to agents
INTRINSIC FACTORS/risk factors
Types of immunologic experiences
Active & Passive
