Week 7: Introduction To Epidemiology Flashcards
The study of distribution of the determinants of health-related states or events in specified populations, and the application of this study to the control of health problems
Epidemiology
What are the stages of the Natural History of a disease?
- Susceptibility
- Subclinical disease
- Clinical disease
- Recovery, disability, or death
A stage of the natural history of a disease where risk factors are present and disease has not yet developed
Susceptibility
A stage of the natural history of a disease where signs and symptoms have already developed
Clinical disease
A stage of the natural history of a disease where there are no signs nor symptoms, but pathologic changes are already occurring in the host
Subclinical disease
What are the four level of prevention?
- Primordial
- Primary
- Secondary
- Tertiary
What level of prevention prevents emergence of risk factors?
Primordial
What level of prevention promotes early detection and monitoring?
Secondary
What level of prevention reduces or eliminate impairments and disabilities?
Tertiary
What level of prevention that controls the exposure to risk factors?
Primary
The levels of prevention that tackles the stage of susceptibility
Primordial and Primary
The level of prevention of subclinical diseases
Secondary
The level of prevention for the stage of clinical disease and recovery, disability, or death
Tertiary
What is the study of the three epidemiologic variables?
Descriptive studies
What are the three epidemiologic variables?
Person, place, time
Which strategy in epidemiology formulates a hypothesis?
Descriptive studies
Which strategy in epidemiology determines association between the exposure and outcome?
Analytical studies
Which strategy in epidemiology tests the hypothesis?
Analytical studies
No manipulation of the exposure variable
Observational
With manipulation of the exposure variable
Experimental studies
What is the separation for the period of communicability of the case?
Isolation
What is the limitation of movement of persons who do not have the disease but are exposed to the agent for not longer than the agent’s maximum incubation period?
Quarantine
What are the two types of strategies at the susceptible population?
- Specific strategies
- Non-specific strategies
Specific strategies
- Chemoprophylaxis
- Immunization
