The study of health issues within populations.
What is epidemiology?
An increase in the number of cases of a disease compared to its normal occurrence at the specified time and place.
What is epidemic?
An individual whom harbors a disease-causing pathogen even though they have recovered.
Who is an active carrier.
The immediate transfer of an agent from a host to a vulnerable host.
What is direct transmission?
The attempt to prevent a disease or disorder before it occurs.
What is primary prevention?
This type of epidemiology uses a comparison group and answers the questions of "why" and "how".
What is analytic epidemiology?
An epidemic extensively affecting the population of a region, country, or continent.
What is pandemic?
An individual who has not shown any symptoms of the disease they have been exposed too and now harbor.
Who is a healthy carrier?
When an agent is carried or transferred by an intermediate mechanism to a vulnerable host.
What is indirect transmission?
Prevention of a disease or disorder before it happens by behavior change on the individual level.
What is active primary prevention?
This type of epidemiology answers the 5 Ws aspects of health-related states or events.
What is descriptive epidemiology?
The normal, constant, or continuous presence of a disease in a community or among a group.
What is endemic?
An individual who is in the recovery phase of a disease but still infectious.
Who is a convalescent carrier?
Bacteria or viruses which transfer between organisms on dust particles or small respiratory droplets.
What is airborne transmission?
Prevention of a disease or disorder without a behavior change on the part of the individual.
What is passive primary prevention?
The ability to produce a desired result in participants of a program compared to those who do not.
What is efficacy?
When victims of a common source outbreak with person-to-person contact cause the disease to spread.
What is mixed epidemic?
An individual who is in the early stages of a disease, showing symptoms, and can transmit the disease.
Bacteria or viruses which transfer between organisms on dust particles or small respiratory droplets.
What is vector-borne transmission?
Health screening and early detection methods to increase chances of a cure or reduce chances of disability or death.
What is secondary prevention?
A program’s ability to produce benefits among participants.
What is effectiveness?
An epidemic which started from a specific source.
What is a common-source epidemic
An individual who can spread a disease at different times or locations.
Who is an intermittent carrier?
Disease transfer using a particular vehicle such as a needle.
What is vehicle-borne transmission?
Providing rehabilitation when a disease, injury, or disorder has occurred and caused damage to reduce disability.
