Epidemiology
The study of health problems in a population
What is Epidemiology?
A person in a population that has been diagnosed with a disease, injury, or disorder
What is a case?
What is portal of exit?
Transmission from the host to a susceptible person or animal through direct means
What is direct transmission?
Trying to prevent a disease or disorder from ever happening through education and health promotion
What is primary prevention?
To quantify associations and test hypotheses between relationships
What is analytic epidemiology?
The first person to be diagnosed with a disease
What is the primary case?
A bacteria, virus or fungi
What is a infectious agent?
When droplets or dust carry a pathogen through the air
What is airborne transmission?
The use of screening to detect a disease or disorder in its early stages
What is secondary prevention?
The charaterization of the distribution on health
What is descriptive epidemiology?
A standard set of criteria to be diagnosed with a disease
What is a case definition?
A host that carries a disease but does not show symptoms
What is a healthy carrier?
When disease is spread from an inanimate object and is picked up by a susceptible host
What is vehicle-borne transmission?
Requires behavior changes to prevent a disease or disorder from happening
What is active primary prevention?
The ability to produce benefits in a program without barriers of entry or difficulty to continue the program
What is effectiveness?
A person who has the symptoms of a disease but has not been clinically diagnosed
What is a suspect case?
An animal or insect that bites an infected host to then carry the disease and have the potential to infect susceptible hosts
What is a vector?
When a pathogen rides on a vector to survive and infect another host
What is mechanical transmission?
Treatment after a disease has been contracted to prevent a disease from getting worse
What is tertiary prevention?
The ability to produce results from a program
What is efficacy?
The first case of a disease that an epidemiologist has discovered
What is a index case?
Where a pathogen can freely replicate and reproduce
What is a reservoir?
When a pathogen goes through changes in its life cycle while inside the host or vector to be transmissible
An attempt to restore an afflicted person to a more productive individual and to raise quality of life
What is rehabilitation?
