Epidemiology
What is epidemiology?
A person with an illness.
What is a case?
Someone who spreads an infection.
What is a carrier?
How the disease is spread.
What are the modes of transmission?
Prevention of a disease before it happens.
What is primary prevention?
The spread of an illness within one specific area or community.
What is an epidemic?
The diagnosis of a person with an illness to identify the illness.
What is a case definition?
Someone exposed to the infection and still has it.
What is an active carrier?
Physical contact between someone infected and someone who is not to spread the infection. (i.e. intercourse)
What is direct transmission?
A change in behavior to prevent a disease from happening.
The three variables of an infection; Host, infectious agent, and environment.
What is the epidemiology triangle?
The first case of a disease in a population.
What is a primary case?
Someone with an infection but is asymptomatic.
Infection transferred by an item or process. (i.e. water, food)
What is indirect transmission?
No change in behavior needed to prevent a disease.
What is passive primary prevention?
Gives a description of who infected, what caused it, what time it took place, and where it took place.
What is descriptive epidemiology?
A person infected by the first case of a disease
What is a secondary case?
Someone who has a pathogen and is still infectious after recovery.
What is a convalescent carrier?
Droplets that can spread an infection.
What is airborne transmission?
The ability of detection to see the disease.
Analyzes hypotheses about relationships involving a comparison group.
What is analytic epidemiology?
Someone with symptoms of an illness but not confirmed to have been diagnosed with the disease.
What is a suspect case?
Someone in the early stages of a disease and can transmit the infection.
What is a incubatory carrier?
Transmission of a disease via an insect (mosquito, flea).
What is vector-borne transmission?
Rehabilitation of symptoms before it gets worse.
What is tertiary prevention?
